In this paper, based on the coupled-mode and carrier rate equations, derivation of a dynamic model and numerically analysis of a MQW chirped DFB-SOA all-optical flip-flop is done precisely. We have analyzed the effects of strains of QW and MQW and cross phase modulation (XPM) on the dynamic response, and rise and fall times of the DFB-SOA all optical flip flop. We have shown that strained MQW a...

The present work reports on the investigations of the magnetization reversal of the system of two glass covered amorphous microwires with circular magnetic bistability. The experiments have been carried out using the transverse magneto-optical Kerr effect in circular and axial magnetic field. The electric current flowing through two wires in opposite directions produced the circular magnetic fi...

Nonlinear optical transmission through periodically nanostructured metal films (surface-plasmon polaritonic crystals) has been studied. The surface polaritonic crystals have been coated with a nonlinear polymer. The optical transmission of such nanostructures has been shown to depend on the control-light illumination conditions. The resonant transmission exhibits bistable behavior with the cont...
