Abstract: A multilayer device includes a substrate having a trench extending along a first surface of the substrate. A first layer disposed on the first surface of the substrate, the first layer comprising a given surface and another surface. A dielectric layer is formed between the given surface of the first layer and the first surface of the substrate. An active region disposed on the other surface of the first layer overlying the trench, wherein at least a portion of the active region resides substantially above a region defined by the trench.

Abstract: An example device in accordance with an aspect of the present disclosure includes a first layer and a second layer to be bonded to the first layer. The first and second layers are materials that generate gas byproducts when bonded, and the first and/or second layers is/are compatible with photonic device operation based on a separation distance. At least one bonding interface layer is to establish the separation distance for photonic device operation, and is to prevent gas trapping and to facilitate bonding between the first layer and the second layer.

Abstract: One example includes an optical device system. The system includes a waveguide that includes a fixed waveguide portion to propagate an optical signal, a semiconductor membrane layer, and a tunable air gap that separates the fixed waveguide portion and the semiconductor membrane layer. The system also includes an optical tuning system to move the semiconductor membrane layer with respect to the fixed waveguide portion in response to a control signal to control a separation distance of the tunable air gap to tune a characteristic of the optical signal.

Abstract: An optical system includes an output waveguide to propagate an optical output signal and a plurality of ring laser systems. Each of the plurality of ring laser systems includes a ring laser to generate a ring laser optical signal and a local waveguide. The ring laser can be optically coupled to the output waveguide to provide a first portion of the ring laser optical signal on the output waveguide as part of the optical output signal, and can be optically coupled to the local waveguide to provide a second portion of the ring laser optical signal on the local waveguide. Each of the plurality of ring laser systems can be to control a phase of the second portion of the ring laser optical signal to provide constructive interference with the ring laser optical signal at an optical coupling of the ring laser and the local waveguide.
