摘要

提出了一种单双驱动马赫-曾德尔调制器(DD-MZM)，用于产生光纤无线电系统(ROF)应用中的残留边带调制方案。由激光二极管(LD)产生的光波使用DD-MZM通过具有π/12、π/6、π/4、π/3和5π/12相位差的射频(RF)信号进行外部调制。这将导致具有不平衡幅度边带的调制光波。仿真结果表明，与光单边带(OSSB)和光双边带(ODSB)调制方案相比，采用π/3和5π/12相位差的光残留边带(OVSB)调制方案能够更好地补偿功率衰落。

A Single DD-MZM for Generating Vestigial Sideband Modulation Scheme in Radio Over Fiber Systems

A single Dual-Drive Mach-Zehnder Modulator (DD-MZM) has been proposed to generate vestigial sideband modulation schemes for radio over fiber system (ROF) applications. Light waves generated by laser diodes (LD) are externally modulated using DD-MZM by Radio Frequency (RF) signals that have the phase difference of π/12, π/6, π/4, π/3, and 5π/12. It is resulting in a modulated optical wave with an unbalanced magnitude sideband. The simulation results show that the Optical Vestigial Sideband (OVSB) modulation scheme with π/3 and 5π/12 phase differences can compensate for power fading better than the Optical Single Sideband (OSSB) and Optical Double Sideband (ODSB) modulation schemes.
