Patent ID: 8634718

Claim:
An optical circuit, comprising: a substrate; an optical coupler provided on the substrate, the optical coupler having first and second inputs and an output, the first input configured to receive a first optical signal and the second input configured to receive a second optical signal, the second optical signal including a polarization state, the optical coupler combining the first and second optical signals into an optical output signal provided on the output of the optical coupler; and an optical fiber having first and second ends and a principle axis, the first end of the optical fiber configured to align with the optical output signal, such that the principle axis of the optical fiber is aligned with the polarization state of the second optical signal, wherein the optical coupler is a wavelength selective combiner, and wherein the first optical signal is a first of a plurality of first optical signals, each including one of a plurality of first wavelengths, and the second optical signal includes a second wavelength, the second wavelength being different than each of the plurality of first wavelengths.
