Abstract

The possibility of electric control over the spectral transfer function of an integrated optical filter comprising a reflection Bragg grating in a photorefractive waveguide is demonstrated for the first time. The filter has a spectral selectivity of 0.15 nm, ensures continuous tuning within ∼0.1 nm, and can be electrically switched on and off. The proposed method of control is effective and has good prospects for practical applications.
