Abstract
Two optical input channels carry two input optical signals in orthogonal polarization states while located at different radial distances relative to a GRIN lens, so that the two input signals exit the lens at different angles. The two signals exiting the lens pass through an optical member having transverse optical axes where the member has different indices of refraction along the two axes. The member passes and combines the two input optical signals into one signal plus a single output optical channel.
