초록

We demonstrate and characterize a volume holographic filter operating at $1.55{\mu}m$ region, which corresponds to the wavelength region of optical communication system. By changing recording times or the angle between writing beams. the reflectivity, the filtered wavelength, and the bandwidth of this filter can be controlled. A center wavelength of 1532.8 nm, reflectivity of 10.7% and a bandwidth with full width at half-maximum of 4.0nm are measured in our experiment.
