Paper Abstract

We demonstrate a narrow-bandwidth tunable optical filter in the telecommunication wavelength region near 1550 nm using photorefractive grating. Holographic gratings could be written by plane waves of green light using CW 532nm laser as recording source. The filter could be tuned by changing the grating spacing by means of changing the incident angle of the recording beams of grating. Through theoretically consideration, we get a diffractive efficiency up to 80% and a bandwidth less than 0.1nm. Besides, we propose a holographic recording setup.
