Abstract

A 20-Gb/s 60 GHz Quadrature Amplitude Modulation (QAM) Radio over Fiber (RoF) system based on injection locking in a Fabry-Perot Laser Diode (FPLD) is described and simulated. In this, optical Millimeter-Wave (MMW) can be generated using low cost FPLD with an external optical injection, using a Distributed Feed Back (DFB) laser diode. The system completely avoids the use of high bandwidth devices to support Radio Frequency (RF). Frequency doubling is also used, such that optical MMW at 37 GHz is generated successfully using injection locking in a FPLD by directly applying 18.5 GHz signal. Simulation result shows good performance for downlink transmission.

在Fabry Perot激光二极管中使用注入锁定的20 gb /S 60 GHz QAM ROF系统

介绍了一种基于注入锁定法布里-珀罗激光二极管(FPLD)的20gb /s 60ghz正交调幅(QAM)光纤无线电(RoF)系统。在这种情况下，光毫米波(MMW)可以使用低成本的FPLD与外部光注入，使用分布式反馈(DFB)激光二极管产生。该系统完全避免了使用高带宽设备来支持射频(RF)。还使用了倍频技术，通过直接施加18.5 GHz信号，在FPLD中使用注入锁定成功地产生了37 GHz的光毫米波。仿真结果表明，该系统具有良好的下行传输性能。
