Patent

CA 2359604

Interleaver/deinterleaver apparatuses for combining/separating optical channels are described. When operating as a deinterleaver, the interleaver/deinterleaver separates an optical signal (e.g. WDM signal) into subsets of optical signals (e.g. channels). In one embodiment, deinterleaving optical signals separates an optical signal into even and odd International Telecommunications Union (ITU) channels. The interleaver/deinterleavers may include isolator components to route optical signals to and from input/output ports. A variety of reflective elements, e.g. quarter wave mirrors, reflective prisms, etalons, can be used for double passing the signals through a birefringent crystal assembly.
