A method and apparatus for communications according to various aspects of the present invention comprises a switching system configured to receive optical signals and direct the optical signals along a selected optical path. The switching system suitably includes more than one switch, and at least one of the switches may include a variable refractive material having a first state and a second state, wherein the optical signal is transmitted via a first path when the variable refractive material is in the first state and the individual channel signal is transmitted via a second path when the variable refractive material is in the second state. The switching system may alternatively or additionally include a switch element having a reflective state and a transmissive state, wherein the optical signal is reflected via a first path when the switch element is in the reflective state and the individual channel signal is transmitted via a second path when the switch element is in the transmissive state. |
