Abstract: An integrated wavelength division multiplexer is described. The integrated wavelength division multiplexer may include a first waveguide core defining a first propagation axis and configured to guide light of a first wavelength and light of a second wavelength, and a second waveguide core defining a second propagation axis and configured to guide the light of the second wavelength. A first portion of the second propagation axis for which the first waveguide core and second waveguide core may be overlapping is oriented at a non-zero angle relative to the first propagation axis. The first waveguide core and second waveguide core may be configured relative to each other to adiabatically couple the light of the second wavelength between the first and second waveguide cores.

Abstract: In part, in one aspect, the disclosure relates to a method for passivating a waveguide of an optical circuit. The method includes etching a suspended waveguide in the optical circuit; the suspended waveguide having a top surface, a bottom surface, and side surfaces; and covering the top surface and side surfaces of the suspended waveguide with a passivation coating having a thickness that ranges from between about 10 nm to about 20 nm. In one embodiment, the method further includes removing one or more coatings from a portion of the optical circuit. The disclosure also relates to various passivated optical silicon circuit embodiments.

Abstract: Cantilevered waveguides suspended above an air cavity in an underlying substrate are described. The waveguide is formed by patterning a waveguide layer in some embodiments, and the air cavity is formed by etching the substrate beneath the waveguide. The topside of the air cavity may be sealed by filling the openings used to etch the cavity with a sealant, such as optical epoxy. In some embodiments, the waveguide is a facet coupler, positioned at a chip facet.

Abstract: Photonic integrated circuits including controllable cantilevers are described. Such photonic integrated circuits may be used in connection with other optical devices, in which light is transferred between the photonic integrated circuit and one of these optical device. The photonic integrated circuit may comprise an optical waveguide having an end disposed proximate to a facet of the cantilever. The orientation of the cantilever may be actively controlled in one or two dimensions, thus adjusting the orientation of the optical waveguide. Actuation of the cantilever may be performed, for example, thermally and/or electrostatically. Orientation of the cantilever may be performed in such a way to align the optical waveguide with an optical device.
