    Abstract: 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.

    Abstract: Instead of monitoring the optical power coming out of a waveguide, a direct method of monitoring the optical power inside the waveguide without affecting device or system performance is provided. A waveguide comprises a p-i-n structure which induces a TPA-generated current and may be enhanced with reverse biasing the diode. The TPA current may be measured directly by probing metal contacts provided on the top surface of the waveguide, and may enable wafer-level testing. The p-i-n structures may be implemented at desired points throughout an integrated network, and thus allows probing of different devices for in-situ power monitor and failure analysis.

    Abstract: 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.

    Abstract: An efficient grating coupler for a semiconductor optical mode includes a tapered edge to couple light between waveguide modes constrained by differing waveguide thicknesses. An optical circuit or laser has a waveguide in a rib or strip waveguide section that is of different height (e.g., having different vertical constraints) than a waveguide section that has a grating coupler through which light passes off-circuit. The tapered edge can couple light between the two waveguide sections with very low loss and back-reflection. The low loss and minimal back-reflection enables testing of the photonics circuit on a wafer level, and improved performance through the grating coupler.

    Abstract: A fast optical modulator or switch with reduced optical loss is disclosed. An apparatus according to aspects of the present invention includes an optical splitter disposed in a semiconductor material. An optical beam having a first wavelength is split by the optical splitter into first and second portions. First and second optical waveguides disposed in the semiconductor material are optically coupled to the optical splitter. The first and second portions of the optical beam are to be directed through the first and second optical waveguides, respectively. The first optical waveguide is also optically coupled to receive a pump optical beam. The pump optical beam has a pump wavelength and a pump power level to amplify and phase shift the first portion of the optical beam of the first wavelength in the first optical waveguide. A diode structure is disposed in the first optical waveguide and is selectively biased to sweep out free carriers from the first optical waveguide generated in response to two photon absorption in the optical waveguide. An optical coupler is disposed in the semiconductor material and is optically coupled to the first and second optical waveguides to combine the first and second portions of the optical beam.
