Abstract
A true-time delay generator for multiple aperture optical beam steering devices. The generator comprises a spectrum spreading element, a dispersive element, and a plurality of tunable optical filters. The spectrum broadening element broadens the spectrum of optical pulses provided to the element via an optical fibre by self phase modulation. The dispersive element imparts a chirp to the wavelengths within the spectrum of the optical pulses. As a result of the chirp, the wavelengths acquire differing delays. The chirped pulses are then simultaneously sent to the plurality of tunable filters, where each filter is set to transmit only a single spectral component from each pulse. Since the spectral components have differing delays, the outputs from the filters are pulses with differing delays. These delays are controlled such that when the pulses are sent to multiple apertures in an optical beam steering device, the pulses will be synchronized when received at a receive point.
