A first portion of incoming light and a second portion of incoming light travel in opposite directions within a first optical waveguide. A ring resonator in-couples the first portion of incoming light and the second portion of incoming light from the first optical waveguide, such that the first portion of incoming light and the second portion of incoming light travel in opposite directions within the ring resonator. A second optical waveguide is disposed to in-couple the first portion of incoming light and the second portion of incoming light couple from the ring resonator, such that the first portion of incoming light and the second portion of incoming light travel in opposite directions within the second optical waveguide away from the ring resonator. One or more photodetector(s) are optically connected to receive the first portion of incoming light and the second portion of incoming light from the second optical waveguide.

Polarization diverse receiver with delays

The present disclosure relates to semiconductor structures and, more particularly, to rib waveguide structures and methods of manufacture. The structure includes: a waveguide structure comprising one or more bends, an input end and an output end; and grating structures which are positioned adjacent to the one or more bends of the waveguide structure.

Waveguide structures

The present disclosure relates to semiconductor structures and, more particularly, to a slot assisted grating based transverse magnetic (TM) pass polarizer and methods of manufacture. The structure includes: a waveguide strip composed of a first type of material and having openings along its length which are positioned to reflect/scatter a propagating electromagnetic waves; and grating fin structures on one or both sides of the waveguide strip which are positioned and structured to reflect/scatter the propagating electromagnetic waves.
