An East-West separable reconfigurable OADM particularly usable as a programmable N x M optical add/drop multiplexer with an efficient pass through of optical channels in a multi-wavelength communication system. The East-West separable reconfigurable OADM uses a grating that separates multi-channel optical signals into a plurality of optical channels, and combines a plurality of optical channels into multi-channel optical signals. Programmable mirrors and beam steerers can direct each optical channel to any of a plurality of fibers coupled to the device. |
