Abstract
An optical bench that provides a core component for a communication system that performs all of the necessary switching, adding, dropping, and manipulating of optical signals entirely in the optical domain. The optical bench comprises a dispersive optical element and a spatial light modulator. Various devices that are useful in the field of optical communication can be produced using the optical bench apparatus as a core component, with the addition of other components to the optical bench. Exemplary optical communication devices that can be built using the optical bench include optical add/drop multiplexers (OADM), Dense Wavelength Division Multiplexing (DWDM) routers, tunable filters, tunable laser sources, optical cross connects, and the like.
