Abstract
An optical switching and delay system for optical encryption and/or optical decryption may comprise a switch bank, a set of optical delay lines, a combiner, and a processor. The switch bank may be configured to receive an optical signal in a first arrangement and route the optical signal to the set of optical delay lines according to a switching arrangement key. The set of optical delay lines may be configured to provide delays to the optical signal. The combiner may be configured to receive the optical signal with delays from the set of optical delay lines and combine the optical signal into a second arrangement. The processor may be configured to receive the switching arrangement key and control the switch bank according to the switching arrangement key. The switching arrangement key may comprise a set of instructions for routing the optical signal.
