Abstract: Disclosed herein are techniques, methods, structures and apparatus that provide a silicon photonics multicarrier optical transceiver wherein both the transmitter and receiver are integrated on a single silicon chip and which generates a plurality of carriers through the effect of an on-chip modulator, amplifies the optical power of the carriers through the effect of an off-chip amplifier, and generates M orthogonal sets of carriers through the effect of an on-chip basis former.

Abstract: Optical transceivers comprising optical loopback circuits are described. The optical transceiver may comprise a housing, which may host a transmitter, a receiver and the optical loopback circuit. The optical loopback circuit may be configured to route at least a portion of a modulated optical signal from the transmitter to the receiver. The optical loopback circuit may comprise tap couplers and/or optical switches. The optical transceiver may be switched between a normal mode and a calibration mode. The optical transceiver may maintain the same fiber connections even when the optical transceiver is switched from one mode to another. The transmitter, the receiver and the optical loopback circuit may be disposed on a common substrate, or on separate substrates.

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.

Abstract: A tunable laser that includes an array of parallel optical amplifiers is described. The laser may also include an intracavity N×M coupler that couples power between a cavity mirror and the array of parallel optical amplifiers. Phase adjusters in optical paths between the N×M coupler and the optical amplifiers can be used to adjust an amount of power output from M-1 ports of the N×M coupler. A tunable wavelength filter is incorporated in the laser cavity to select a lasing wavelength.
