Abstract
A photonic computing system, preferably including an input module, a computation module, and/or control module. The photonic computing system can include one or more optical filter banks, such as in the computation module and/or any other suitable modules. Each optical filter bank preferably includes a plurality of photonic bandgap phase modulators. Each photonic bandgap phase modulator preferably includes a set of photonic crystal segments. The photonic crystal segments can preferably be controlled to transition light propagation between two or more photonic bands.
