Latest Patents

Matthew Chang holds a patent for a "Multibeam radio frequency photonic beamformer using a multi-signal slow light time delay unit." This invention is designed to transmit or receive multiple RF input signals from various antennas. The beamformer receiver incorporates several optical modulators that modulate each RF input signal onto an optical carrier, with each carrier operating at a different wavelength. Additionally, the receiver features optical amplifiers that adjust the optical power of the carriers based on weighting inputs, generating weighted optical carriers. The system also includes multi-beam optical true-time delays (TTD) that produce time-delayed optical carriers, along with detectors that convert these carriers into electrical signals representing the received RF input signals.
