ABSTRACT:
The present invention provides a method and a circuit architecture whereby a time delay for optical signals in an integrated optical circuit is implemented in a hybrid configuration. For example, a hybrid time delay circuit could be implemented with a three chip set composed of a switch chip 34 placed between two delay chips 36,38. The delay chips may include one or more delay loops 44 and preferably an associated bypass loop for each delay loop 42. The switch chip contains an optical switch 20 for each delay loop on the delay chips and may contain switch control circuitry or an interface to external switch control circuitry.
