ABSTRACT:
An antenna beamformer consisting of optical irises coupled to Wavelength Division Multiplexers (WDMs). The ports of the WDMs are coupled to lens ports, where each lens port corresponds to a different antenna beam. The optical irises are optical filters with selectable center frequencies and selectable passband widths. Selection of different center frequencies and passband widths enables the selection of different ports of the WDMs, which allows the selection of one or more antenna beams. The beamformer may also have controllable delay lines to provide for additional beam steering.
