Fabrication of Quasi Phase Matched Structures for Frequency Conversion in Photopolymers Doped with Push-Pull Chromophores

摘要

Organic materials possessing quadratic non linear optical (NLO) properties are now part of the optical material panel available for applications. Up to now, the patterning of their optical properties for device fabrication is commonly achieved by the lithographic techniques derived from the microelectronic domain. We propose here an alternative method that allows a direct patterning of the NLO properties. The objective is to manufacture quasi phase matched devices for optical frequency conversion in guided mode and in the regime of free propagation.
