[IEEE 2019 Photonics & Electromagnetics Research Symposium - Fall (PIERS - Fall) - Xiamen, China (2019.12.17-2019.12.20)] 2019 Photonics & Electromagnetics Research Symposium - Fall (PIERS - Fall) - A Frequency Hopping Communication System Using Directly Modulated Laser Based Optical Heterodyne Technique
摘要： This paper proposes a Frequency Hopping (FH) communication system with a novel frequency synthesis method. Considering that the existing frequency synthesis methods are inevitably limited by the electronic device bandwidth, a combination of directly modulated laser (DML) and optical heterodyne technique is proposed as a hopping frequency source. The principle of the method is presented and a dual frequency hopping system in E band is carried out through simulation to veri?ed the feasibility of the proposed method. This frequency synthesis method supports high radio frequency, ultra-wideband and high hopping speed.

Complete Scene Reconstruction by Merging Images and Laser Scans
摘要： Optical fibre transmission has enabled greatly increased transmission rates with 10 Gb/s common in local area networks. End users find wireless access highly convenient for mobile communication. However, limited spectrum availability at microwave frequencies results in per-user transmission rates limited to much lower values, e.g., 500 Mb/s for 5-GHz band IEEE 802.11ac. Extending the high data-rate capacity of optical fiber transmission to wireless devices requires greatly increased carrier frequencies. This paper will describe how photonic techniques can enable ultrahigh capacity wireless data distribution and transmission using signals at millimeter-wave and TeraHertz (THz) frequencies.
