Abstract

We demonstrate a 4-bit optical true time-delay module for synthetic aperture radars based on the integration of polymer channel waveguide and electro-optic Bragg gratings. The demonstrated device is a truly integrated module that eliminates the most difficult packaging problem associated with the delicate interfaces between optical fibers and optical switches. The total insertion loss of the 4-bit optical true-time-delay line is less than 3 dB with switching time <50 □s and driving voltage of 25 V.
