We present a narrow-bandwidth interference filter in an optical monomode LiNbO3:Ti:Fe channel waveguide operating in the infrared wavelength region around lambda = 1.55 mu m. The filter consists of a thermally fixed refractive-index Bragg grating recorded with visible green light by use of a holographic technique. In a first approach we measure a reflectivity for the infrared light of 60% and a linewidth (FWHM) of 0.11 nm. (C) 1998 Optical Society of America.
