Abstract
A photonic band-gap structure (a small periodic corrugation at the surface) present in a planar nonlinear waveguide can enhance the nonlinear process of second-subharmonic generation provided that all interactions are phase matched. Compared with a perfectly quasi-phase matched waveguide, better values of squeezing and higher intensities of the output fields are reached under these conditions. squeezed-light generation, nonlinear waveguide, photonic-band-gap structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
