Abstract :
A multiple beam former using multichannel chirped fiber grating (MCFG) and tunable optical delay lines is investigated in this paper. The simulation results shown in this paper exhibited that it could form two beams, which could be operated squint-free and independently from each other at 6 GHz. The use of a MCFG along with tunable optical delay lines has greatly reduced the system complexity and components requirements. Moreover, our proposed beam-former is able to operate using fewer tunable laser sources than other similar approaches. Successfully addressing this problem in the components cost would make the implementation of the scheme far more feasible.
