Abstract: An optical device is disclosed, including a phase delay, a first adiabatic coupler adapted to receive an input signal and adapted to be optically coupled to an input of the phase delay, and a second adiabatic coupler adapted to be optically coupled to an output of the phase delay. The second adiabatic coupler includes a first waveguide including a first portion optically coupled to the first output and including a first width, and a second waveguide including a second portion optically coupled to the second output and comprising a second width that is approximately equal to the first width.

Abstract: Aspects described herein include an optical apparatus comprising at least a first Bragg grating of a first stage. The first Bragg grating is configured to transmit a first two wavelengths and to reflect a second two wavelengths of a received optical signal. The optical apparatus further comprises a second Bragg grating of a second stage. The second Bragg grating is configured to transmit one of the first two wavelengths and to reflect the other of the first two wavelengths. The optical apparatus further comprises a third Bragg grating of the second stage. The third Bragg grating is configured to transmit one of the second two wavelengths and to reflect the other of the second two wavelengths.

Abstract: An optical waveguide structure includes a rotator having a dual-layer core. A first layer of the dual-layer core may include a tapering portion. A second layer of the dual-layer core may include a rib portion disposed on the tapering portion. The combination of the rib portion and the tapering portion may receive a pair of optical signals, one being polarized in a TE mode and the other being polarized in a TM mode, and convert them to a pair of TE mode optical signals.
