title: Loss measurements in thin-film optical waveguides.
abstract: An apparatus for the measurement of attenuation of light in thin-film waveguides is described. It involves a prism that rides on a liquid film along the guide and couples the light out of the guide. A spatial resolution of ~0.5 mm and an accuracy of 0.02 dB/cm were achieved.
