ABSTRACT:
A length dependent, optical time delay/filter device for electrical signals having a single integrated optical switching circuit and only two optical time delay components connected thereto. The optical time delay components are each made up of a plurality of optical fibers of varying lengths. Depending upon which fibers an optical signal (converted from an incoming electrical signal) passes through determines the time of travel of the optical signal through the device. This optical signal is then converted back into an electrical output signal which is, as a result thereof, time delayed/filtered.
