ABSTRACT:
The disclosure describes a switchable optical delay device which is small, inexpensive, lightweight, has high cross-talk isolation, and is capable of sub-microsecond switching times. The delay device uses low-reflection terminations, a single input, and a single output to minimize cross-talk. The device is preferably integrated onto a substrate in either a trombone-shaped configuration or a more compact nested configuration.
