| Abstract: | Photorefractive volume holographic Bragg grating was written into LiNbO3 crystal using two-beam interference by controlling the angle of the beams.This photorefractive holographic grating was used in an optic communication system as a filter and tested using ASE light source and spectrometer.The diffraction efficiency at 1 548 nm was 10% and the full width at half maximum was 4 nm. |
