Dual-Wavelength Fiber Laser for 5G and Lidar Applications

Abstract

This chapter illustrates the generation of the millimeter wave in the range of 10 GHz to 110 GHz using a tunable dual-wavelength erbium-doped fiber laser. It also describes the utilization of these millimeter-waves as carrier frequencies for the transmission of 16-QAM with a data rate of 10 Gb/s over a radio over fiber and free space optics links. The chapter also includes the utilization the millimeter-waves, that are generated in the designed dual-wavelength fiber laser, for estimating the target range and velocity of multiple radar cross-section defined automotive targets by developing a frequency-modulated continuous-wave photonics-based radar system in the presence of environmental fluctuations. We believe that the proposed dual-wavelength fiber laser described in this chapter will reveal the potential of realizing different microwave-photonic systems/networks, for instance, 5G/6G networks, self-driving vehicles, photonics-based radar systems, surveillance, and monitoring.
