A simple integrated Young interferometer sensor was prepared on a glass substrate with a pair of single-mode straight channel waveguides $75\mu \text{m}$ apart. A tapered thin film of ${\text{TiO}}_2$ was locally deposited on one channel to form a composite waveguide sensing arm with a greatly enhanced evanescent field. With the prism-coupling method a single beam of laser light was simultaneously launched into the two channels to yield a high-contrast interference pattern. Refractive-index sensitivity of the interferometer and its response to protein adsorption were investigated by using a slit-photodetector assembly to interrogate the sensor signal. The factors affecting the fringe contrast were analyzed.
