Theory of low-threshold optical switching in nonlinear phase-shifted periodic structures
نویسندگان
چکیده
The theory of phase-shifted nonlinear periodic structures operating in the stationary regime is presented. The transmissive properties of the structure are analyzed by solution of the corresponding set of nonlinear coupledmode equations exactly. Extremely low switching intensities are found for the special case of ly4-shifted structures. An all-optical low-intensity switching configuration that uses a wavelength-tunable source and a ly4-shifted nonlinear structure is proposed. Advantages of the phase-shifted distributed-feedback design in all-optical switching applications are discussed.

Optical switching in A/4-shifted nonlinear periodic structures
We show that A/4-shifted distributed-feedback nonlinear devices can be used as an all-optical switch at relatively low input intensities. The A/4 shift opens a narrow transmission window whose peak position within the stop band depends on the input intensity, a feature that can be used for low-power optical switching. The nonlinear coupled-mode approach is used to analyze the stationary operati...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...
