We design and demonstrate a compact, narrow-linewidth integrated laser based on low-loss
silicon nitride waveguides coupled to a III-V gain chip. By using a highly confined optical …

We demonstrate the generation of quantum-correlated photon pairs combined with the
spectral filtering of the pump field by more than 95 dB on a single silicon chip using …

We demonstrate a III-V/silicon hybrid external cavity laser with a tuning range larger than 60
nm at the C-band on a silicon-on-insulator platform. A III-V semiconductor gain chip is …

Photonic integrated circuits (PICs) allow for the rapid advancement of a wide range of optical
devices on a compact platform, making them more useful and readily available in the …

We report a Ge-on-Si photodetector without doped Ge or Ge-metal contacts. Despite the
simplified fabrication process, the device shows a responsivity of 1.14 A/W at− 4 V reverse …

Abstract Coronavirus disease 2019 (COVID-19) is a newly emerging human infectious
disease that continues to develop new variants. A crucial step in the quest to reduce the …

We demonstrate hybridly integrated narrow-linewidth, tunable diode lasers in the InP/GaAs-
Si_3N_4 platform. Silicon nitride photonic integrated circuits, instead of silicon waveguides …

We demonstrate integrated basic photonic components and Bragg gratings using 60-nm-
thick silicon-on-insulator strip waveguides. The ultra-thin waveguides exhibit a propagation …
