Paper Abstract

Recently, the desired very high throughput of 5G wireless networks drives millimeter-wave (mm-wave) communication into practical applications. Phased array technique is required to increase the effective antenna aperture at mm-wave frequency. Integrated solutions of beam-forming/-steering are extremely attractive for practical implementations. In this talk, we review our recent progress and latest research on optical mm-wave beam steering. The remotely tunable integrated mm-wave beamformer based on optical true time delay is explored. The on-chip TTD network is realized by the architecture of arrayed waveguide grating feedback loop. The high-speed photo-diodes (>40GHz) are also integrated to reduce the package-induced power loss and cost. To allow its application in practical scenarios, the electronic integrated circuits including multiple-channel automatic power controlled trans-impedance amplifiers are designed to accommodate the electrical signal after photodiodes. Based on the integrated circuits, we have successfully demonstrated a 38-GHz beam-steered fiber-wireless system for 5G indoor coverage.
