متن کاملFemotosecond switching in a dual-core-fiber nonlinear coupler.
We report all-optical switching of 100-fsec pulses in a fused-quartz dual-core-fiber directional coupler. The length of the device is 0.5 cm, and the switching power is 32 kW. Pulses are routed to either of two separate fiber guides, depending on the input power. Measurements of pulse reshaping by the nonlinear coupler provide compelling evidence of the device's ability to response on a femotos...
متن کاملAll-optical Switching Structure Using Nonlinear Photonic Crystal Directional Coupler
In this paper, a new all-optical switching structure is proposed and analyzed. Switching is accomplished by embedded Kerr nonlinear rods in the coupling region of a photonic crystal directional coupler. We show that by modifying the supermodes dispersion curves, the switch length can be reduced 22% with respect to similar structures. Finite-Difference TimeDomain and Plane Wave Expansion methods...
متن کاملNonlinear surface lattice coupler.
We study two-component surface solitons in a pair of linearly coupled truncated waveguiding arrays with the Kerr nonlinearity. Symmetric solitons have a very small stability area, while those that are antisymmetric and asymmetric are stable in vast regions. Below a critical value of the coupling constant, branches of the symmetric and asymmetric modes separate, and accordingly, asymmetric solit...
متن کاملQuantum 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...
