Abstract
The present invention generally relates to optical communication systems, and more particularly, to an apparatus combining microelectromechanical systems (MEMS) elements and optical wavelength division multiplexing/demultiplexing (WDM) elements for optical wavelength selective add/drop application. Wherein, optical fiber arrays or optical planar waveguide arrays are used as the input terminal and the output terminal of multiple optical signals. Moreover, 1.times.N one-dimensional micro-mirror arrays manufactured by using the MEMS technology are applied to change the transmitting directions of the optical signal of each channel between the input terminals and the output terminals, thus, it achieves the purpose of switching the optical signals from one channel of input terminals to another corresponding channel of output terminals. If the above-mentioned optical fiber arrays or optical planar waveguide arrays are replaced or combined with arrayed waveguide gratings (AWG) as multiplexers and demultiplexers, this apparatus can be applied as a wavelength selective optical add/drop multiplexer (OADM), or a reconfigurable optical add/drop multiplexer (ROADM), and is capable of achieving the high-channel-counts demands of all-optical network in the future.
