Abstract

A multi-beam optical beamforming network with low loss is proposed based on the integrated arrayed waveguide grating (AWG). By using the diffraction effect of AWG, the optical multiple beamforming architecture is reduced significantly since the true time delays for different wavelength can be realized simply by employing only one module. The 3 channels of 88 AWG for dense wavelength division multiplexing (WDM) with low loss is fabricated successfully, and then the integrated optical multiple beamformer for eight-element is demonstrated. Experimental results show that the insertion loss for each beamformer is reduced to 5.64 dB. Furthermore, the number of simultaneous beamformer achieves to be 4, which could cover the airspace from -36° to 18°.
