Electro- and thermo-optic effects on multi-wavelength. Solc filters based on chi((2)) nonlinear quasi-periodic photonic crystals

Abstract

We investigate electro- and thermo-optic effects on multi-wavelength. Solc filters based on chi((2)) nonlinear quasi-periodic photonic crystals. The multi-wavelength. Solc filters are composed of two building blocks A and B, in which each containing a pair of antiparallel poled domains, arranged as a Fibonacci sequence. The transmittances at filtering wavelengths can be modulated from 0 to 100 % by applying an external voltage but the filtering wavelengths are unchanged. The filtering wavelengths can be tuned by varying temperature. As temperature decreases, the filtering wavelengths increase (similar to -0.45 nm/degrees C). (c) 2008 Optical Society of America.
