Optical coupler for heterogeneous integration
Abstract
In an optical apparatus, an introduced semiconductor device is heterointegrated on a silicon-based platform containing a silicon-based waveguide. A polymeric waveguide is optically coupled to the introduced semiconductor device and overlies at least a portion of the silicon-based waveguide. The polymeric waveguide is conformed as a multimode interference (MMI) coupler between the introduced semiconductor device and the silicon-based waveguide. At least the polymeric waveguide, and in embodiments, also the silicon-based waveguide, is tapered with a shape that effectuates optical coupling to the silicon-based waveguide.
