Abstract :
The authors report the use of a sol-gel film as an overlay guide on an integrated optic buried channel waveguide to selectively couple out near-infra-red wavelengths. The coupling wavelength is shown to be dependent on the thickness and index of the overlay and on the polarisation of the guided light
