Abstract
A narrow-band reflection (stop-band) optical filter has been constructed in a planar optical waveguide made by ion exchange of silver in soda-lime glass. A comparison of the measured and computed performance of this optical filter is given. The filter has a bandwidth of 0.35 nm at a centre wavelength of 611 nm.Keywords
