Nonlinear directional coupler for polychromatic light.
We demonstrate that a nonlinear directional coupler with special bending of waveguide axes can be used for all-optical switching of polychromatic light with a very broad spectrum covering all of the visible region. The bandwidth of the suggested device is enhanced five times compared with conventional couplers. Our results suggest novel opportunities for the creation of all-optical logical gate...
متن کاملPulsed squeezed-light generation in x (2) nonlinear waveguides
We present a brief history of experimental studies of quadrature squeezing, a tutorial on the physical origin and theory of squeezing, and our experimental study of squeezing by means of x (2) (second-order) nonlinear waveguides. We recently obtained 28% squeezing in quasi-phase-matched LiTaO3 waveguides, using picosecond pulses. The amount of squeezing appears to be limited primarily by blue-l...
متن کاملA novel design for all-optical NAND/NOR/XOR gates based on nonlinear directional coupler
In this paper a novel all-optical logic NAND, NOR and XOR gate based on nonlinear directional coupler theory is demonstrated. We use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. In other words, while a beam with 4 W/μm in power considered as logical one, the output is NAND gate and if a beam w...

متن کاملDynamic behaviour in a nonlinear directional coupler with feedback
A new kind of resonator based on a nonlinear directional coupler with feedback is presented. The steady states are found and the map of the system is iterated, showing the existence of bistability, period doubling and chaos. The dependence of the dynamic features is discussed in terms of the parameters of the two different schemes of feedback studied in this work. A new device based on one of t...
