ABSTRACT:
In some embodiments, an optical switch includes multiple individually-retractable wedge switching prisms stacked in a longitudinal channel, corresponding plural transverse-translation rhomboid prisms extending transversely away from the longitudinal channel, and corresponding plural fiber collimators oriented longitudinally and aligned along a transverse line on both sides of the longitudinal channel. To switch light to a selected fiber collimator, its corresponding wedge switching prism is inserted in the longitudinal channel to deflect light to a corresponding transverse-translation prism and on to the selected fiber collimator; the other switching prisms are retracted from the channel. In some embodiments, longitudinally-adjacent switching prisms are oriented in opposite directions. A reverse-deflection wedge prism can be provided between each switching prism and its corresponding transverse-translation prism. The described preferred systems allow improved system stability, as well as ease of manufacturing and alignment.
