A new technique for generating a continuous range of true time delay values is introduced. Heating optical ΓΏber in order to change the e ective index of the guided mode produces time delays. A 45-m section of single-mode silica ΓΏber is demonstrated to produce a continuous range of time delay values
## Abstract A novel optical true timeβdelay (TTD) feeder for phasedβarray antennas incorporating a fiber Bragg grating (FBG) prism and optical fibers with metal film deposited on their cleaved ends is proposed. By arranging a metalβfilm reflector at one end of the fiber delay line with FBGs written
