Abstract
An optical add/drop module includes an add channel, an input channel, a drop channel and an output channel, with each channel aligned to transmit or receive light reflected from a common mirror in at least one state of the add/drop module. Rotating the mirror changes the state of the module. In the module's add/drop state, light from the input channel reflects from the mirror into the drop channel and light from the add channel reflects off the mirror to the output channel. In the module's pass through state, light from the input channel reflects off the mirror into the output channel and light from the add channel reflects off the mirror to a position other than the drop channel. Arrays of add, input, drop and output channels can be coupled to a linear array of independent micro-electromechanical mirrors to provide an integrated set of optical add/drop modules.
