    摘要： Acousto-optic and ultrasonic devices are described which are dependent for their operation on certain germanium-containing compositions of the chalcogenide family of glasses. The acoustooptic devices made from these glasses exhibit high efficiencies when compared to those of devices constructed of earlier materials. The ultrasonic devices exhibit acoustic losses comparable to those of devices made from fused silica.

    摘要： A high-speed optical modulator comprised of a fluid oscillator having first and second output channels and means for alternately switching a fluid stream into the first and second output channels. The first output channel serves as part of an optical prism, and air and liquid are alternately present in the first output channel to provide different indices of refraction so that light passing through the optical prism is alternately partially and totally reflected.
