摘要：

We describe Wavelength-addressed 3- and 6-b fiberoptic true time-delay (TTD) lines implemented using ultraviolet-inscribed Bragg gratings, The 3-b delay line is fabricated from an array of discrete-and uniform-period Bragg gratings, and a minimum time delay of 9.09 ps is selectable, making it suitable for phased-array antenna (PAA) beamforming control at RF frequencies of up to about 3 GHz with 10 degrees phase resolution, The 6-b delay line is fabricated using a chirped-period Bragg grating, and is suitable for beamforming control at RF frequencies of up to similar to 48 GHz, With 10 degrees phase resolution.
