Abstract: A novel, simple, compact, and integrable scheme of reconfigurable and ultrafast photonic logic gate is demonstrated, based on a single semiconductor optical amplifier (SOA) and able to ...

In particular, full-swing output XOR and NAND logic gates are demonstrated using the same physical four-transistor circuit.

Coventry City Council raked in an estimated £2million in bus gate fines last year ... cameras which record all vehicles using the bus lanes. "After identifying those vehicles that are not ...
