All-optical binary logic unit (BLU) using frequency encoded data
All-optical frequency encoded data based binary logic unit is proposed. Binary logic unit is indispensible for optical computing and data processing. Nonlinear polarization rotation based frequency conversion by SOA is exploited here. The scheme of operation requires very low power for switching action. Proposed scheme is effective for WDM communication network.
