Abstract :
A 2-D multiple beams beam-former using multi-channel chirped fiber grating (MCFG) and tunable optical delay lines is investigated in this paper. The simulation results shown in this work exhibited that it was capable of forming beams in 2-D plane, which could be operated independently from each other at 8 GHz. The use of a MCFG along with tunable optical delay lines has greatly reduced the system complexity and components requirements. Simulations also indicated that our proposed scheme is more robust against group delay ripple, an inevitable error in every grating.
