Multiwavelength Solc filters based on chi((2)) nonlinear quasiperiodic photonic crystals with Fibonacci sequences

Abstract

We demonstrate that a chi((2)) nonlinear quasiperiodic photonic crystal can act as a multiwavelength Solc filter. The chi((2)) nonlinear quasiperiodic photonic crystal consists of two building blocks A and B, in which each containing a pair of antiparallel poled domains, arranged as a Fibonacci sequence. The filtering wavelengths are analyzed with the Fibonacci sequence parameters such as the quasiperiodic indices and the average lattice parameter. The filtering efficiency can be tuned by the lengths of poled domains. (c) 2007 American Institute of Physics.
