Abstract :
A multi beam-former using multi-channel chirped fiber grating (MCFG) and tunable optical delay lines is proposed in this paper. Simulation results shown that it could form two beams, which could be operated squint-free and independent from each other at 6 GHz. The use of MCFG incorporation with tunable optical delay lines has greatly reduced the system complexity and components requirement. Moreover, our proposed beam-former is more robust against group delay ripple, which is the main reason for directivity error in other beam-former using chirped fiber grating.
