Abstract: Structures for a polarizer and methods of forming a structure for a polarizer. A first slotted waveguide component is positioned over a first waveguide core, and a second slotted waveguide component positioned over the first slotted waveguide component. The first slotted waveguide component includes a second waveguide core and a third waveguide core separated by a first slot, and the second slotted waveguide component includes a fourth waveguide core and a fifth waveguide core separated by a second slot. The first waveguide core is laterally aligned with the first slot and the second slot.

Abstract: Optical coupler structures include a waveguide having waveguide metamaterial segments aligned along a first line. A second insulator is on the first insulator and the waveguide metamaterial segments. A coupler structure is in the second insulator and has coupler metamaterial segments aligned along a second line. The first line and the second line are parallel and within a plane. A portion of the waveguide overlaps a portion of the coupler structure. The waveguide metamaterial segments intersect the plane and have first widths perpendicular to the plane, and the first widths have a first taper along the first line. The coupler metamaterial segments intersect the plane and have second widths in the direction perpendicular to the plane. The second widths have a second taper along the second line that is different from the first taper of the first widths where the waveguide overlaps the coupler structure.

Abstract: Structures including a grating coupler and methods of fabricating such structures. The structure includes a waveguide core, a bend, and a grating coupler coupled to the waveguide core by the bend. The grating coupler includes grating structures that are positioned with a spaced relationship in a layer stack above the bend.

Abstract: Structures for a filter and methods of fabricating a structure for a filter. The filter is coupled to a waveguide core. The filter includes a first plurality of grating structures positioned adjacent to a first section of the waveguide core and a second plurality of grating structures positioned adjacent to a second section of the waveguide core. The first plurality of grating structures are configured to cause laser light in a first portion of a wavelength band to be transferred between the first section of the waveguide core and the first plurality of grating structures. The second plurality of grating structures are configured to cause laser light in a second portion of a wavelength band to be transferred between the second section of the waveguide core and the second plurality of grating structures.
