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.
