Paper Abstract

We report here a novel way to fabricate fiber LPG using moire pattern amplitude mask (MPAM). Theoretical analysis of diffraction effect on MPAM has revealed that geometric optics rules are followed when area concerned is so close to diffractive grating that even Fresnel approximation can not be used. Experimental result of grating written in As2S3 fiber support the theoretic conclusion. And the temperature dependence is reported also.
