Abstract
An optical depolarizer includes a birefringent block, a reflector coupled to the block, a first input port for providing polarized light to the block and an output port configured to receive polarized light from the block. The depolarizer optionally includes a non-reciprocal combination-device having a principal direction and including a first birefringent wedge, a second birefringent wedge, and a non-reciprocal rotating element. The non-reciprocal rotating element can be a Faraday rotator. The birefringent block can be optically coupled to the non-reciprocal combinatoin device. The optical depolarizer can include a lens that is optically coupled to the first wedge. The optical depolarizer can include a capillary for holding at least a PM optical fiber and an output optical fiber.
