摘要： An optical wavelength multiplexer/demultiplexer is disclosed to use double reflections on the same filter twice through help of a mirror to enhance the reflection channel isolation without comprising optical performance. It employs only one filter and one mirror on a support substrate. The optical wavelength multiplexer/demultiplexer offers a smaller size than a conventional one and lower cost of manufacturing.
