Abstract
The present invention provides an improved switchable interleaved channel separator device. The switchable interleaved channel separator device utilizes an adjustable reflective non-linear interferometer, which performs both switching and wavelength polarization sorting functions, so that overall complexity of the device is reduced. Further, because the adjustable non-linear interferometer is a reflection element, signal light paths are folded back upon one another so as to realize an overall reduction in the device's size, as well as the capability of performing optical couplings predominantly or wholly at a single side or at adjacent sides of the device.
