A high-efficiency 50 GHz InGaAs multimode waveguide photodetector
TL;DR: In this paper, a side-illuminated p-i-n photodetector with a multimode waveguide structure is proposed, which has an external quantum efficiency of 56% without AR coating and 68% with AR coating.
Proceedings ArticleDOI
Design of high-speed and high-sensitivity photodiode with an input optical waveguide on semi-insulating InP substrate
TL;DR: In this paper, an InGaAs waveguide photodiode (WGPD) consisting of a multimode waveguide configuration was designed to obtain high sensitivity with no carrier-transit-time limitation.
