Abstract

An optical true-time delay generation scheme based on WSS for adaptive null steering is proposed. The system is based on optically-switched fiber TTD technology. Take the advantages of the LCoS-based programmable WSS, arbitrary multiple true-time delays to generate multiple nulls can simultaneously be synthesized by control the routing of the optical radio frequency signal between the wavelength selective switches. We simulate the scheme with Optisystem and Matlab, the results confirm the scheme is able to achieve null depth over 50dB.
