Abstract
A tunable narrowband (FWHM= 2.5 GHz) 1.55 mu m reflective drop filter is realised in an iron doped indium phosphide crystal. The index grati ng results from the photorefractive effect via an interference pattern . The grating period is determined by the wavelength of the laser diod e which provides the two counterpropagating writing beams.
