Packaged and hybrid integrated all-optical flip-flop memory

A fully-packaged hybrid-integrated all-optical flip-flop, where InP-based semiconductor optical amplifiers are assembled onto a planar silica waveguide board, is demonstrated. It is shown experimentally that the flip-flop can dynamically toggle between its two states by injecting 150 ps optical pulses with 6 dBm peak power via its set and reset port.
