Abstract: A photonic chip includes a device layer and a port layer, with an optical port located at the port layer. Inter-layer optical couplers are provided for coupling light between the device and port layers. The inter-layer couplers may be configured to couple signal light but block pump light or other undesired wavelength from entering the device layer, operating as an input filter. The port layer may accommodate other light pre-processing functions, such as optical power splitting, that are undesirable in the device layer.

Abstract: A MOSCAP phase adjuster includes two conductive regions with a thin insulating region therebetween, where charge is accumulated or depleted. In conventional MOSCAP modulators, the conductive and insulating regions are superposed layers, extending horizontally parallel to the substrate, which limits waveguide design and mode confinement, resulting in reduced phase shift performance. An improved MOSCAP phase adjuster and method of fabricating a MOSCAP phase adjuster includes depositing the material for the second conductive region beside and over top of the first conductive region after oxidation, and selectively etching the material to form the second conductive region.

Abstract: Disclosed herein are a photonic integrated circuit (PIC) including an edge coupler (EC) and method thereof. In some embodiments, the EC is optically coupled to a first waveguide at an inner end of the EC. In some embodiments, the PIC is in contact with an optical fiber at an outer end of the EC. The EC may include a plurality of waveguide cores located on a plurality of waveguide layers. The waveguide cores of the plurality of waveguide cores are located apart from each other and configured to adapt a mode size of a beam of light between a larger mode size at the outer end of the EC and a smaller mode size at the inner end of the EC.

Abstract: For multi-mode interference (MMI) couplers that have a plurality of input and output ports, e.g. 4×4, a large number of modes may be supported in the multimode region, e.g. >10, as the width of the MMI core grows larger. In order for MMI couplers to form good images, the supported modes preferably have low modal phase error, which can't be achieved using a conventional single layer design. Accordingly, a multi-mode interference (MMI) coupler comprising an MMI core comprising a plurality of waveguide core strips alternating with a plurality of cladding strips solves the aforementioned problems.

Abstract: A mode-matched waveguide Y-junction with balanced or unbalanced splitting comprises an input waveguide, expanding from an input end to an output end, for expanding the input beam of light along a longitudinal axis; first and second output waveguides extending from the output end of the input waveguide separated by a gap. Ideally, each of the first and second output waveguides includes an initial section capable of supporting a fundamental super mode, and having an inner wall substantially parallel to the longitudinal axis, and a mode splitting section extending from the initial section at an acute angle to the longitudinal axis.
