Many visual and robotics tasks in real-world scenarios rely on robust handling of high speed motion and high dynamic range (HDR) with effectively high spatial resolution and low noise. Such stringe…
A cascade array structure and depleted layer thickness design method of uni-traveling-carrier photodetector (UTC-PD) for terahertz applications is proposed. The cascade array structure can increase…
We experimentally demonstrate a THz integrated circuit with a pixel-array-based orbital-angular-momentum (OAM) mode converter for the generation and multiplexing of multiple data-carrying OAM beams…
We experimentally demonstrate a Brillouin fiber laser (BFL) with a low threshold and narrow linewidth at 2 μ m employing a chalcogenide As 2 S 3 fiber as the Brillouin gain fiber. The As 2 S 3 fib…
Conventional techniques for demodulating phase/frequency-modulated (PM/FM) optical signals either require a sophisticated frequency-stable laser or employ a discriminator with poor characteristics.…
Optimal LED size is an important topic for high-speed UV-C wireless communication but still lacks sufficient investigation. In this work, we study the size effect of UV-C LEDs based on the entire c…
We demonstrate a high-energy and high-average power Mamyshev oscillator based on a high performance large-mode-area step-index germanosilicate-cladding Yb-doped fiber. The oscillation of higher-ord…
Vehicle Re-Identification (ReID) is of great significance for public security and intelligent transportation. Large and comprehensive datasets are crucial for the development of vehicle ReID in mod…
In this paper, we propose a high-speed PIN photodiode with a composite absorption layer. It supports a 3-dB bandwidth of 43 GHz and can be used in 100 Gbit/s optical receivers. The composite absorp…
