Nonclassical Properties of Pulsed Second-Subharmonic Generation in Photonic-Band-Gap Structures

Abstract

A waveguide made of LiNbO3 with a periodic linear corrugation on its surface is analyzed from the point of view of squeezed-light generation. It is shown that scattering of nonlinearly interacting optical fields caused by the corrugation improves efficiency of the nonlinear process under certain conditions. These conditions are found approximately analytically and confirmed numerically. The linear corrugation can be tuned both into the pump as well as second-subharmonic field in order to improve efficiency of the nonlinear process. The analysis provides a detailed understanding of the role of all parameters of the waveguide and this enables to specify optimum values of parameters to achieve the best values of squeezing. In pulsed regime the right choice of spectral modes is important to observe squeezing. These modes are found using the Bloch-Messiah reduction of the appropriate Green functions.
