We propose a method for 2D multiple beam generation without causing extraneous beams in the ASTRO architecture. By simply adding a circular light block (spatial filter) at the center of the polygon mirror on the ASTRO true time delay generator, all t

2D multiple beam steering in the Acoustically STeered and ROtated (ASTRO) true time delay generationarchitecture is described. The architecture is capable of generating 2D multiple beams without causing any extraneous beams. The system can be used as

Recent interest in WDM increasingly demands a faster tunable spectral filter with a narrower bandwidth with weak sidelobes to permit a larger number of wavelength channels within the erbium-doped fiber amplifier (EDFA) passband. However, most current

A new 2-D true time delay (TTD) generation system architecture for phased array antennas is described. The method uses fiber chirp gratings and acousto-optic beam deflectors. By combining free-space optics and guided optics, the device complexity in
