Abstract: A silicon photonics module may include a waveguide for receiving and transmitting an optical beam. The silicon photonics module may include a tap connected to the waveguide to allow measurement of an optical power of the optical beam. The silicon photonics module may include one or more splitters connected to the waveguide to tap a portion of the optical beam from the waveguide and to split the portion of the optical beam into a first part and a second part. The silicon photonics module may include a first Mach-Zehnder interferometer (MZI) to filter the first part to allow measurement of an optical power of the filtered first part. The silicon photonics module may include a second MZI to filter the second part to allow measurement of an optical power of the filtered second part.

Abstract: A mode-converting optical coupler may include a secondary waveguide to guide light in one or more secondary optical modes, and a primary waveguide to guide light in one or more primary optical modes, each adiabatically coupled to a secondary optical mode of the secondary waveguide having a secondary mode index. Each primary optical mode of the primary waveguide may have a first primary mode index near a first end and a second primary mode index near a second end. The first primary mode index may be lower than the second primary mode index. The secondary mode index may be between the first primary mode index and the second primary mode index. The primary waveguide may include a plurality of silicon core structures including a central core structure arranged between a first neighboring core structure and a second neighboring core structure.

Abstract: A photonic integrated circuit may include a substrate and an optical waveguide integrated with the substrate. The optical waveguide may include a bend section, wherein a bend shape of the bend section is defined by a curvature function to suppress waveguide mode conversion.
