All-optical switching in lithium niobate directional couplers with cascaded nonlinearity.
نویسندگان
چکیده
We report on intensity-dependent switching in lithium niobate directional couplers. Large nonlinear phase shifts that are due to cascading detune the coupling between the coupler branches, which makes all-optical switching possible. Depending on the input intensity, the output could be switched between the cross and the bar coupler branches with a switching ratio of 1:5 and a throughput of 80%.

Nonlinear directional coupler in periodically poled lithium niobate.
Nonlinear wave propagation was investigated experimentally in coupled waveguides by means of the cascaded nonlinearity in quasi-phase-matched second-harmonic generation. With a specially designed wave-vector-mismatch distribution along the propagation axis, cascading was optimized for low fundamental depletion. High-contrast, ultrafast all-optical switching with switching powers of tens of watt...
متن کاملMultistep cascading in periodically poled directional couplers.
We suggest a novel scheme for multistep cascaded parametric processes based on a periodically poled nonlinear directional coupler and derive the conditions for simultaneous phase matching of the second-harmonic generation and sum-frequency mixing processes. We predict an efficient wavelength conversion by the cascaded third-harmonic generation from the third optical communication window (1.53-1...
متن کاملDirectional coupling for solitary waves in quadratic nonlinearity
The propagation of temporal solitary waves, formed in the second-order nonlinear medium, is analysed in waveguide directional couplers. The influence of the thirdorder nonlinearity on the switching effect is also presented. Recently, the great effort of nonlinear guided-wave phenomena research is focused on the cascaded second-order process which can produce relatively large intensity-dependent...
متن کامل1 × 4 signal router using three
This paper presents an overview of integrated optical signal routing based on the principle of electro-optic effects. There are some specific types of materials whose refractive index changes due to the application of the electric field. Lithium-niobate (LiNbO 3) and gallium arsenide are some important electro-optic materials. Due to the application of the voltage across electrode present in on...
متن کاملAll-Optical Pulse Retiming Based on Quadratic Cascading in a Periodically Poled Lithium Niobate Waveguide
We demonstrate an all-optical technique for the elimination of timing jitter in short pulse transmission systems. The technique relies on pulse pre-shaping followed by optical switching in a periodically poled lithium niobate waveguide via cascaded second harmonic and difference frequency generation. ©2010 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (130.3730)...
