摘要：
Deep etched Bragg reflector gratings in lnGaAs-InP waveguide structures have been realized. The width of the waveguide was 2 mu m and was dry etched to a depth of more than 1.5 mu m using CH4/H-2-based chemistry. The Bragg reflectors were designed to be first order and to have a large bandwidth - with one to three slots in the waveguide structure. The single slot reflector has a width of 190 nm and the period of other two-slots grating is 420 nm and slot width of similar to 200 nm. (c) 2007 WILEY-VCH Verlag GmbH &Co. KGaA, Weinheim.
