This paper describes the use of an integrated optical Bragg-reflector as a chemo-optical sensor. It is shown that these types of Bragg-reflectors for a wavelength of 630 nm can be realized with a bandwidth smaller than 0.2 nm in a optical channel waveguide. Measurements show that a refractive index change of the waveguide cladding of can be detected.read more
