Abstract

A tunable optical grating (12) is provided in a photorefractive polymer waveguide (20). The grating (12) is formed by recording a hologram corresponding to a Bragg grating of a desired period in the waveguide (20) with suitable optical addressing means. When it is desired to retune the grating (12) the optical addressing means is used to record a new hologram corresponding to a Bragg grating in the waveguide (20).
