An exposed Bragg grating incorporated into a planar waveguide was used to form a refractive index sensor. The high sensitivity to subtle changes allowed the study of surface functionalisation and binding within a microfluidic system. OCIS codes: (280.4788) Optical sensing and sensors; (230.7380) Waveguides, channelled. Planar waveguides can be written with a UV-laser into photosensitized silica to produce a wide range of optical devices. Careful modulation of interfering beams allows Bragg
