Quantum Zeno effect in a nonlinear coupler
The dynamics of a spontaneous downconversion process with the idler mode coupled to an auxiliary mode is analysed. Depending on the presence or absence of nonlinear phase mismatch, a Zeno or anti–Zeno effect is found. This behavior is understood by using the dressed modes picture of the device. A possibility to achieve a quasi–phase– matching by careful adjustment of coupling strength is pointe...

متن کاملQuantum Zeno and anti-Zeno Effects: An Exact Model
Recent studies suggest that both the quantum Zeno (increase of the natural lifetime of an unstable quantum state by repeated measurements) and anti-Zeno (decrease of the natural lifetime) effects can be made manifest in the same system by simply changing the dissipative decay rate associated with the environment. Here, we present a model which incorporates the effect of the environment in an ex...
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...
