Abstract

We describe wavelength-addressed 3- and 6-b fiberoptic true time-delay (TTD) lines implemented using ultravioletinscribed 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° 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 ~ 48 GHz with 10° phase resolution. © 1997 IEEE.
