Abstract :
A new grating based beam-former is presented which can synthesise a large number of beams with the minimum number of interconnects. A partitioned WDM grating topology is also described which removes the frequency and beat noise limits, and results are presented for the ultimate capacity of grating true-time-delay beam-formers.
