    Abstract: Disclosed are edge couplers having a high coupling efficiency and low polarization dependent loss, and methods of making the edge couplers. In one embodiment, a semiconductor device for optical coupling is disclosed. The semiconductor device includes: a substrate; an optical waveguide over the substrate; and a plurality of layers over the optical waveguide. The plurality of layers includes a plurality of coupling pillars disposed at an edge of the semiconductor device. The plurality of coupling pillars form an edge coupler configured for optically coupling the optical waveguide to an optical fiber placed at the edge of the semiconductor device.

    Abstract: A device includes an optical isolator disposed between adjacent optical waveguides along a direction. The optical isolator has vertical or horizontal dimensions that are different than at least one of the optical waveguides. The vertical and horizontal dimensions are greater than vertical and horizontal dimensions of at least one of the waveguides. In various embodiments, the structure of the optical isolator can be a planar structure, a columnar periodic structure, or a grating structure. The material of the optical isolator can be a metallic material or a dielectric material. In some embodiments, the optical isolator and the optical waveguides are used to enhance the performance of an optical multiplexing device.

    Abstract: In some embodiments, the present disclosure relates to a device having a first waveguide and a second waveguide arranged over a substrate. The first waveguide has a first input terminal and a first output terminal, wherein the first input terminal is configured to receive light. The second waveguide is arranged laterally beside the first waveguide and has a second input terminal and a second output terminal. The second input terminal of the second waveguide is configured to receive light. The first waveguide further includes a first portion that has a different structure than surrounding portions of the first waveguide. The second waveguide further includes a second portion that has a different structure than surrounding portions of the second waveguide. The first waveguide is spaced apart at a maximum distance from the second waveguide at the first portion and the second portion.
