Abstract

The development of all-optical switches based on organic polymers is of great interest in photonics. An effective nonlinear n₂ coefficient may be obtained by cascading of the second-order nonlinear susceptibility.^1,2 A large χ⁽²⁾(2ω; ω, ω) effect and quasi-phase-matching is achieved in polymeric waveguides by a spatially periodical electric poling field in direction of light propagation z.
