摘要： Embodiment of present invention provide a micro-optics module. The module includes a glass body of pentagon shape having five side surfaces including an upper side surface, a left side and a right side surface next to the upper side surface, a lower side surface next to the left side surface, and a 5th side surface next to and between the lower side surface and the right side surface. The glass body is adapted to, upon incident of a first optical signal at the left side surface, cause the first optical signal to propagate toward and exit the glass body at the right side surface and, upon incident of a second optical signal at the right side surface, cause the second optical signal to reflect back at the left side surface; reflect back at the 5th side surface; and finally exit the glass body at the upper side surface.

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.
