Abstract Frequency‐sweeping laser sources play a critical role in the accurate 3D mapping of frequency‐modulated continuous‐wave (FMCW) LiDAR systems, whose chirp linearity greatly impacts measurement precision. Although various pre‐distortion algorithms have been proposed to reduce nonlinearity, these open‐loop methods can rapidly suppress nonlinearity but they are susceptible environmental variations and often exhibit subpar performance long‐range detection scenarios. In contrast,...
Deep ultraviolet (DUV) light-emitting diodes (LEDs) have attracted widespread attention in communication because of their lack background noise interference day-blind communications, but low luminous efficiency and response frequency cannot meet the requirements non-visual optical systems. AlGaN-based micro-LEDs (μ-LEDs) can provide high light output power (LOP) due to smaller chip size, they also withstand current density enhanced diffusion uniformity. Thus, matrix-type DUV μ-LEDs are...
Abstract Possessing a long coherent length, high repetition rate, and fast frequency‐sweeping laser sources with narrow linewidth is crucial components in frequency‐modulated continuous‐wave (FMCW) light detection ranging (LiDAR) systems. While these attributes are realized individually standalone devices, the integration of features into single represents significant advancement field. In this study, hybrid integrated that achieves 9 kHz, wide frequency‐modulation response extending up to...
We demonstrate a high-efficiency silicon optical phase shifter based on silicon-Sb2Se3 hybrid integrated waveguide. The field has large confinement in the Sb2Se3 material, leading to high wave modulation efficiency upon change of Sb2Se3. is initiated by electro-thermal heating generated highly durable graphene microheater positioned between strip and slab To effectively couple with single-mode waveguides, we design two-layer taper structure as mode spot size converter. Utilizing this...

These results indicate that coherent transition responsible for...
We describe the temperature-dependence polarization properties of grating-gated AlGaN/GaN heterostructures at terahertz frequencies. Using finite-difference time-domain method, it was demonstrated that as temperature increases, resonant frequency incident light red-shifted. Simultaneously, a shorter gate length leads to higher frequency. In addition, lower temperature, coupling efficiency radiation and plasmon is higher. our simulation results, maximum modulation depth 88%; 800 nm lattice 77...
