Abstract: An apparatus includes a cladding layer and a plurality of waveguides. The cladding layer includes a central axis. The plurality of waveguides are disposed within the cladding layer and receive a light from a light source. The plurality of waveguides have refractive indices that are adjustable to change a mode of the light such that the mode of the light is steered towards the central axis.

Abstract: The present disclosure describes systems and methods for detecting temperature in an electro-optical circuit (e.g., an electro-optical transceiver). According to an embodiment, an electro-optical circuit includes a photonic integrated circuit and an electronic integrated circuit. The photonic integrated circuit includes an optical component and a first resistor positioned by the optical component. The electronic integrated circuit determines a temperature for the optical component based on a first resistance of the first resistor.

Abstract: A compact micro electrical mechanical actuated ring-resonator includes a bus waveguide disposed on a platform; a ring resonator disposed on the platform, including at least a first optical coupler, wherein the ring resonator is optically coupled with the bus waveguide; and a selective waveguide disposed on a piezoelectric cantilever mounted in a trench defined in the platform, wherein the selective waveguide includes a second optical coupler and is controllable to selectively adjust a coupling ratio between the first optical coupler with the second optical coupler by physically changing a distance between the first optical coupler and the second optical coupler.
