Abstract:
1. An optical time delay module comprising: a. a substrate of a smart material that changes dimension in response to an analog electrical control signal; b. a plurality of optical time delay elements connected in series in an optical circuit disposed on said substrate, an initial time delay element in said series being responsive to an optical input to said module; c. a plurality an optical output couplers wherein each of said optical output couplers is operationally connected between each time delay element in said series, the optical output couplers providing a plurality of tapped optical outputs from said module with different optical delays controlled by said analog electrical control signal; d. wherein each time delay element is arranged on or in said substrate of said smart material to change an amount of time delay imposed thereby in response said substrate changing dimension in response to changes in said analog electrical control signal.
