Photonic image-free mixer based on a dual-parallel Mach-Zehnder modulator and fiber dispersion for radio-over-fiber system
IEEE Photonics Journal(2019)
摘要
In this paper, a simple image rejection mixer based on the dispersion effect in the single mode fiber is proposed and experimentally demonstrated for the radio-over-fiber (RoF) system. The key idea is to control the DC bias voltages of the dual parallel Mach-Zehnder modulator (DPMZM) to compensate for the desired components and eliminate the image induced components simultaneously during the fiber...
