Abstract:Semiconductor laser diodes (LDs) generate high output powers with high power conversion efficiencies. While broad-area LDs are favored for high-power applications, narrow-waveguide LDs are in demand for their single-mode characteristics. However, LDs suffer from device failures caused by catastrophic optical damage (COD) due to elevated self-heating at high operating currents. It is critical to understand the COD mechanism in these devices to enhance their reliability and operating output power. In this study, we investigated the self-heating and temperature characteristics of LDs with varying waveguide widths to uncover the cause of their failure mechanism. We assessed the performance, junction, and facet temperatures of the narrow (W=7 mu m) and broad waveguide (W=100 mu m) LDs. The narrower waveguide LDs achieved and operated at higher output power densities but, surprisingly, maintained lower junction and facet temperatures. Additionally, we employed a thermal simulation model to analyze heat transport characteristics versus LD waveguide widths. The simulation results showed that narrower waveguide LDs exhibit improved three-dimensional heat dissipation, resulting in reduced junction and facet temperatures and, thus, enhanced reliability. Our simulations align well with the experimental data. The findings demonstrate a transition in heat dissipation characteristics from broad to narrow waveguide behavior at approximately 50 mu m width. These results clarify the fundamental reasons behind the superior reliability of narrower waveguide LDs and provide valuable guidance for LD thermal management.

Abstract:The Earth 2.0 (ET) space mission has entered its phase B study in China. It seeks to understand how frequently habitable Earth-like planets orbit solar-type stars (Earth 2.0s), the formation and evolution of terrestrial-like planets, and the origin of free-floating planets. The final design of ET includes six 28 cm diameter transit telescope systems, each with a field of view of 550 square degrees, and one 35 cm diameter microlensing telescope with a field of view of 4 square degrees. In transit mode, ET will continuously monitor over 2 million FGKM dwarfs in the original Kepler field and its neighboring fields for four years. Simultaneously, in microlensing mode, it will observe over 30 million I < 20.5 stars in the Galactic bulge direction. Simulations indicate that ET mission could identify approximately 40,000 new planets, including about 4,000 terrestrial-like planets across a wide range of orbital periods and in the interstellar space, similar to 1000 microlensing planets, similar to 10 Earth 2.0s and around 25 free-floating Earth mass planets. Coordinated observations with ground-based KMTNet telescopes will enable the measurement of masses for similar to 300 microlensing planets, helping determine the mass distribution functions of free-floating planets and cold planets. ET will operate from the Earth-Sun L2 halo orbit with a designed lifetime exceeding 4 years. The phase B study involves detailed design and engineering development of the transit and microlensing telescopes. Updates on this mission study are reported.

Abstract:The U-shaped frame is a crucial component of the theodolite. The coaxial accuracy of the bearing holes on both sides of the U-shaped frame directly affects the pitch-axis accuracy and further influences the angular measurement precision of the theodolite. The machining of the bearing holes on both sides of the U-shaped frame with a long span requires the use of methods such as a large-stroke boring machine or the assembly and adjustment of the frame's own structure. However, considering various factors such as the manufacturing cost, manufacturing time, and machining precision of the U-shaped frame, neither of the above methods is the optimal solution. This paper proposes a splicing design method for the U-shaped frame based on the principle of one side and two pins positioning. This method solves the problems of low coaxial accuracy and difficult machining of bearing holes in U-shaped frames with long spans. Through multiple splicing accuracy tests of the coaxiality of the bearing holes in a U-shaped frame with a span of 1500 mm, the average coaxiality error of the bearing holes is 0.023 mm, with a maximum value of 0.038 mm, which is less than the theoretical maximum coaxiality error of 0.058 mm. The coaxiality tolerance precision level is close to Grade 5, which meets the requirements for the use of high-precision theodolite.

Abstract:A polarization reconfigurable 2I2 array with enhanced bandwidth is analyzed and designed, which consists of one simplified feed network and four antenna elements. Characteristic mode analysis is used to explain radiation character-istics of element antenna and slot coupling feed is employed to enhance the bandwidth. By changing the on-off state of four p-i-n diodes loaded in simplified feed network, linear polarization (LP), left-handed circular polarization (LHCP) and right-handed circular polarization (RHCP) could be obtained respectively. The designed 2I2 antenna array with a compact size of 2.01 lambda(0) x 1.96 lambda(0) x 0.06 lambda(0) is simulated and measured. The measured-10-dB impedance bandwidth is 4.38-5.72 GHz for the LP state. The overlapped -10-dB impedance bandwidth and 3-dB axial ratio bandwidths are 4.32-5.44 GHz for both RHCP and LHCP states. The maximum gain reaches 7.9 dBi and the overlapped relative bandwidth of three polarization states is over 21%.

Abstract:Spectral calibration sources are essential for the calibration and characterization of spectroscopic detection equipment. This paper presents the design of an inductively coupled light source as a spectral calibration source. We employed a longitudinal magnetic field inductive discharge design, conducted a simulation analysis of the magnetic field distribution within this design, and solved the drift-diffusion equations to obtain the electron temperature and energy distribution of the generated plasma. The designed RF circuit has a stable resonant frequency at 13 MHz, and the operating power can be adjusted between 0 and 20 W. This device demonstrates excellent performance and stability, offering a longer lifespan compared to traditional calibration sources.

Abstract:Mild cognitive impairment (MCI) is an irreversible, gradual neurological disease and one of the main complications of epilepsy. The scale proves effective in detecting cognitive impairment, but it relies on labor-intensive processes and is easily affected by patients' subjective behavior. Using machine learning methods to analyze EEG data is a promising alternative for detecting MCI. However, the increasing amount of EEG data affects the efficiency of detection. We innovatively propose a novel deep learning (DL) network based on residual blocks to overcome this issue. The DL network aims to efficiently detect cognitive impairment in epilepsy patients by analyzing unique EEG data collected during the Attention Network Test (ANT) and predicting patients' scale score. The suggested network consists of four phases: band-pass filter, spatial convolution block, residual block, and classifier. The entire proposed framework comprises four steps: collecting EEG data, preprocessing the raw data, extracting data features, and classification between MCI subjects and normal ones. Data from 92 patients with epilepsy were used for training and performance evaluation of the network. The classification performance of the proposed network has been compared with that of ResNet18, ResNet34, EEGNet, and FBCNet. The experimental results shows that the proposed network achieved the best classification performance among all five tested networks. The proposed network could also be used for MCI prediction, in which task it achieved about 0.05 in MAE while predicting the score of MOCA for patients, demonstrating a considerable predictive result. Five- fold cross-validation was used to assess the framework's stability.

Abstract:Eye fatigue, a prominent symptom of computer vision syndrome (CVS), has gained significant attention in various domains due to the increasing diversification of electronic display devices and their widespread usage scenarios. The COVID-19 pandemic has further intensified the reliance on these devices, leading to prolonged screen time. This study aimed to investigate the effectiveness of utilizing eye movement patterns in discriminating fatigue during the usage of electronic display devices. Eye movement data was collected from subjects experiencing different levels of fatigue, and their fatigue levels were recorded using the T/CVIA-73-2019 scale. The analysis revealed that features related to the pupils demonstrated a high level of confidence and reliability in distinguishing fatigue, especially related to pupil size. However, features associated with fixations, such as fixation duration and frequency, did not significantly contribute to fatigue discrimination. Furthermore, the study explored the influence of subjective awareness on fatigue discrimination. By modifying the experimental settings and considering the subjects' subjective perception, it was observed that individual consciousness and self-awareness played a crucial role in fatigue discrimination. The implications of these findings extend beyond the field of computer vision syndrome, offering potential applications in developing interventions and strategies to alleviate eye fatigue and promote eye health among individuals who extensively use electronic display devices.

Abstract:Our primary goal is to significantly enhance the output power of broad-area laser diodes (LDs) for improved cost-effectiveness of laser systems and broaden their applications in various fields. To achieve this, we implemented an epitaxial design with low internal optical loss and high internal efficiency in agreement with our simulations. We present comprehensive results of high-power single-emitter and bar LDs spanning wavelengths from 915 to 1064 nm. To demonstrate power scaling in single emitter LDs, we utilized waveguide widths from 100 to 500 mu m, achieving a continuous-wave (CW) maximum output power of 74 W at 976 nm under room temperature conditions, limited by the heatsink temperature control. We also build fiber-coupled modules with single-emitters operating at 1.6 kW. Employing the same epitaxial structure in 1-cm wide laser bars, we demonstrated 976 nm laser bars operated at 100 A CW with 113 W output and a high efficiency of 72.9% at room temperature. Additionally, we achieved 500 W room-temperature CW laser bars at 940 nm. For long wavelength designs at 1064 nm, 500 W output was obtained in quasi-continuous-wave (QCW) operating laser bars. Our results represent significant advancements in obtaining high power and efficient LDs across a broad wavelength range and configuration.
