Abstract: Disclosed herein is an integrated photonics device including a frequency stabilization subsystem for monitoring and/or adjusting the wavelength of light emitted by one or more light sources. The device can include one or more selectors that can combine, select, and/or filter light along one or more light paths, which can include light emitted by a plurality of light sources. Example selectors may include, but are not limited to, an arrayed waveguide grating (AWG), a ring resonator, a plurality of distributed Bragg reflectors (DBRs), a plurality of filters, and the like. Output light paths from the selector(s) can be input into one or more detector(s). The detector(s) can receive the light along the light paths and can generate one or more signals as output signal(s) from the frequency stabilization subsystem. A controller can monitor the wavelength and can adjust or generate control signal(s) for the one or more light sources to lock the monitored wavelength to a target wavelength (or within a targeted range of wavelengths).

Abstract: A waveguide structure and a method for splitting light is described. The method may include optically coupling a first waveguide and a second waveguide, where the optical coupling may be wavelength insensitive. The widths of the first and second waveguides may be non-adiabatically varying and the optical coupling may be asymmetric between the first and second waveguides. A gap between the first and second waveguides may also be varied non-adiabatically and the gap may depend on the widths of the first and second waveguides. The optical coupling between the first and second waveguides may also occur in the approximate wavelength range of 800 nanometers to 1700 nanometers.

Abstract: This disclosure relates to the layout of optical components included in a photonics integrated circuit (PIC) and the routing of optical traces between the optical components. The optical components can include light sources, a detector array, and a combiner. The optical components can be located in different regions of a substrate of the PIC, where the regions may include one or more types of active optical components, but also may exclude other types of active optical components. The optical traces can include a first plurality of optical traces for routing signals between light sources and a detector array, where the first plurality of optical traces can be located in an outer region of the substrate. The optical traces can also include a second plurality of optical traces for routing signals between the light sources and a combiner, where the second plurality of optical traces can be located in regions between banks of the light sources.

Abstract: Configurations for an optical coupler that includes waveguides that provide asymmetric mode confinement. The optical coupler may include first and second rib waveguides, and the width of the shoulder of at least one rib waveguide may taper to provide the asymmetric mode confinement. In some instances the shoulders of one or both rib waveguides may have different heights in a central region of the optical coupler.
