Corrugation gratings for fast integrated complementary metal-oxide semiconductor photodetectors: implementation and
Abstract:
We present simulation experiments to show the feasibility of using a corrugation grating structure at the silicon-silicon dioxide interface to reduce photon-absorption depth and therefore to improve response times for shallow p-n junction photodiodes for use in the optical interconnection of very-large-scale-integrated circuits. A fabrication method that uses standard complementary metal-oxide semiconductor fabrication steps is presented for generating the grating structure. Simulations show reduction in 1/e photon-penetration depth to one half the value that is expected with no grating.
