Ultraviolet detectors are widely used in space exploration, military affairs, and disinfection. To further improve the responsivity and response time, we propose and demonstrate AlN three-dimension…
The proliferation of wireless broadband services have significantly raised the demand for high data rates. Due to the limited bandwidth of radio frequency (RF) bands that are currently in use for c…
We propose two types of temperature-compensated all-fiber sensors based on a novel laser-machined Fabry-Perot interferometer (FPI) whose sensitivity is adjusted by controlling the FPI gauge length …
Laser pointing unit using tilting orthogonal double prisms (TODP) opens up a promising avenue for fine pointing in free-space laser communication, which can steer the laser beam with a pointing pre…
