Abstract: A photonic integrated circuit may be coupled to an optical fiber and packaged. The optical fiber may be supported by a fiber holder during a solder reflow process performed to mount the packaged photonic integrated circuit to a circuit board or other substrate. The optical fiber may be decoupled from the fiber holder, and the fiber holder removed, after completion of the solder reflow process.

Abstract: A method for steering a beam is disclosed. According to the method, a scene is scanned with a surface emitting grating optically coupled to a free propagation region. The free propagation region is optically coupled to waveguides. The waveguides are disposed at different angles to the surface emitting grating. The scanning includes scanning in a first dimension by cycling through a cross connect to illuminate each waveguide of the waveguides. Scanning in a second dimension is performed by tuning a wavelength of light used to illuminate the waveguides.

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.
