High-power, single-frequency lasers are important in the applications of coherent optical communication, Doppler wind lidar, and remote sensing. Here, a 10-kHz, 353-μJ, single-frequency, 574-ns, 1…
Geiger-mode InGaAsP/InP single photon avalanche photodiode (SPAD) with a low dark count rate (DCR) of 870 Hz at a photon detection efficiency (PDE) of 20% at 1064 nm is achieved for a 40 micron dia…
A photonic-assisted reconfigurable LO harmonic downconverter with simultaneous image-rejection and RF self-interference cancellation (SIC) for in-band full-duplex communication is proposed and expe…
Ex-situ rapid thermal treatments of 1–2.5 μm extended wavelength In 0.83 Ga 0.17 As/In 0.83 Al 0.17 As photodetector epiwafers on InP substrate were investigated. Enhanced photoluminescence inte…
We firstly propose a roadmap for thedesign of high repetition rate (∼100 MHz) Tm-doped ultrafast fiber laser with an emission wavelength above 2000 nm. This roadmap is confirmed by both theoretic…
A photonics-assisted frequency conversion and self-interference cancellation approach is proposed and experimentally demonstrated for in-band full-duplex (IBFD) communication. Carrier suppressed si…
Problem definition: We study a problem of a retailer that orders from competing strategic suppliers subject to independent or correlated disruptions and responds by setting the retail price on deli…
The dark current and the photo response characteristics of extended wavelength In 0.83 Ga 0.17 As/InP photodetectors (PDs) with n-In 0.83 Ga 0.17 As absorber doped to 8×10 15 , 7×10 16 and 1×10 …
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…
