Abstract
A birefringent wedge is used to multiplex beams of the same or similar wavelength. The multiplexing system has a compact construction and does not require beam splitters or right angle prisms. The birefringent wedge may also be used to polarization demultiplex an incoming multiplexed communication beam. The invention may be used to increase the data-carrying capacity of optical fiber.
