Efficient Two Photon Absorption for 400-nm Remote Optical Control at 2-μm Waveband in a Low-loss Multimode Silicon Waveguide

Abstract

Efficient TPA for 400-nm range remote control at 2-μm waveband is experimentally realized with 8.9-dB ER by C-band pump using a low-loss multimode silicon waveguide, indicating fully utilized advantages at both C and 2-μm wavebands.
