Abstract:
An optical output device (164) includes a moncrystalline silicon substrate (102) and multiple light sources (168a-168n) formed of compound semiconductor materials. An accommodating buffer layer (104) lies between the light sources (168a-168n) and the substrate (102). An optical interconnect (170), such as a waveguide, is formed over the multiple light sources (168a-168n) and connects them to an output port (172). The accommodating buffer layer (104) is a layer of monocrystalline oxide spaced apart from the silicon substrate (102) by an amorphous interface layer (106) of silicon oxide, and is lattice matched to both the underlying silicon substrate (102) and the waveguide (170). Any lattice mismatch between the accommodating buffer layer (104) and the underlying silicon substrate (102) is taken care of by the amorphous interface layer (106).
