Abstract :
In this paper, the negative effect of group delay ripples on optical beamformers using chirped grating is investigated. A promising solution in the form of hybrid approach for optical beamformer is also presented. Both transmitting and receiving systems using this approach have been demonstrated and examined against the group delay fluctuations.
