Optical interleaver
This invention provides a novel wavelength filter module that reduces the number of components required in an optical interleaver, and can be configured in various ways suitable for practical applications. An optical interleaver of the present invention incorporating such a wavelength filter module is simpler and more compact in design, lower in insertion losses, polarization dependent loss (PDL) and cost, while more reliable in performance. The optical interleaver of the present invention can be advantageously configured as a multiplexer, de-multiplexer, or a router.
