High-speed and high-responsivity hybrid silicon/black-phosphorus waveguide photodetectors at 2 μm

Yanlong Yin, Rui Cao, Jingshu Guo +13

Silicon photonics is being extended from the near-infrared (near-IR) window of 1.3-1.5 μm for optical fiber communications to the mid-infrared (mid-IR) wavelength-band of 2 μm or l…
