Abstract
We propose and demonstrate a configurable and flexible photonic true-time delay (PTTD) line for integrated transmitting/receiving optically controlled phased array antenna (PAA) based on combinations of cascaded linear chirped fiber Bragg grating (LCFBG). A large-scale beam steering angle close to the limit and high angle resolution can be obtained by precisely configuring the parameters including dispersion coefficient and the numbers of cascaded LCFBG; Multi-beams for different beam steering angles are acquired synchronously.
