Abstract:
1. A method for fabricating an integrated optical receiver comprising: providing a silicon on insulator (Sal) wafer comprising a silicon handle layer, a buried oxide (BOX) layer, a silicon waveguide layer and a hard mask (HM) oxide layer; etching a taper in the HM layer and the silicon waveguide layer; etching a V-groove in a portion of the silicon layer; filling taper and the V-groove with oxide to form a total internal reflection (TIR) mirror structure; planarizing the TIR mirror structure; bonding a silicon wafer to the TIR mirror structure; flipping the SOl wafer over; removing the silicon handle layer; and fabricating a high-speed photo-detector (PO) over the V-groove.
