Robust optical control of an optical-amplifier-based flip-flop.
We demonstrate new optical techniques for externally controlling the latchable output power of a semiconductor-optical-amplifier-based flip-flop. Optical 'set' and 'reset' signals increase and decrease the re-fractive index, respectively, via cross-phase modulation (XPM). Set signals, which deplete the carrier density, have wavelengths between 1533 and 1568 nm, and powers as low as 22 microW. R...
متن کاملRemote optical control of an optical flip-flop.
We experimentally demonstrate control of a holding-beam-enabled optical flip-flop by means of optical signals that act in a remote fashion. These optical-control signals vary the holding-beam power by means of cross-gain modulation within a remotely located semiconductor optical amplifier (SOA). The power-modulated holding beam then travels through a resonant-type SOA, where flip-flop action oc...

متن کاملRobust Lyapunov-based Control of MEMS Optical Switches
In this paper, a robust PID control scheme is proposed for Micro-Electro-Mechanical-Systems (MEMS) optical switches. The proposed approach is designed in a way which solves two challenging and important problems. The first one is successful reference tracking and the second is mitigating the system nonlinearities. The overall system composed of nonlinear MEMS dynamics and the PID controller is ...
