摘要： Inverted 45° semiconductor mirrors as vertical optical couplers for PIC chips, particularly optical receivers and transmitters. An inverted 45° semiconductor mirror functions to couple light between a plane in the PIC chip defined by thin film layers and a direction normal to a top surface of the PIC chip where it may be generated or collected by an off-chip component, such as a wire terminal. In an exemplary embodiment, a (110) plane of a cubic crystalline semiconductor may provide a 45° facet inverted relative to a (100) surface of the semiconductor from which light is to be emitted. In further embodiments, a (110) plane may be exposed by undercutting a device layer of a semiconductor on insulator (SOI) substrate. Alternatively, a pre-etched substrate surface may be bonded to a handling wafer, thinned, and then utilized for PIC waveguide formation.

摘要： A vertical total internal reflection (TIR) mirror and fabrication thereof is made by creating a re-entrant profile using crystallographic silicon etching. Starting with an SOI wafer, a deep silicon etch is used to expose the buried oxide layer, which is then wet-etched (in HF), opening the bottom surface of the Si device layer. This bottom silicon surface is then exposed so that in a crystallographic etch, the resulting shape is a re-entrant trapezoid with facets These facets can be used in conjunction with planar silicon waveguides to reflect the light upwards based on the TIR principle. Alternately, light can be coupled into the silicon waveguides from above the wafer for such purposes as wafer level testing.

摘要： Embodiments of the invention use crystallographic etching of SOI wafers with a (110)-oriented epi layer to form both the vertical input facet and the re-entrant mirror. Proposed layout design combined with proposed orientation of the epi enables both vertical facets and re-entrant (upward-reflecting) mirror facets to be made in a single wafer-level wet etch process.
