Abstract
An optical device according to the present invention is disclosed which comprises a first optical fiber and a second optical fiber disposed adjacent to each other, the first fiber being optically configured to receive incident light; a polarization dependent reflector having a preferred axis; a common lens configured to optically couple the first and second fibers to the polarization dependent reflector; and a third optical fiber coupled to the polarization dependent reflector through a second lens. The device may be characterized in that the optical device is aligned such that incident light launched into the polarization dependent reflector is provided to the second fiber at both a predetermined angle and a predetermined polarization; and such that incident light launched into the polarization dependent reflector is launched into the third fiber at a predetermined polarization.
