Abstract
We present an experimental demonstration of radio beamforming using an optical chip for application in K-band satellite communication. Via coherent combination of four RF channels, close to 12 dB beamforming gain is obtained. As a result, the transmission capacity is enhanced from 8-QAM, 5.81 Gbps to 32-QAM, 9.68 Gbps of multi-carrier data. For 4 channel beamforming, error-free performance (BER<1E-12) is obtained with 8-QAM data. The tuning of the optical beamforming chip is done electronically via a software interface by a computer.
