Abstract

Wavelength division multiplex millimeter wave light source row includes multiple wavelength comb type light signals generator, one optical demultiplexer, multiple multimode laser, and one multiplexer. The optical demultiplexer makes demultiplexing multiple wavelength comb type light signals. Multimode laser is input for each distributive wavelength segment. The multimode laser generates mode-locking light signals in dual mode with mode space in millimeter wave frequency. The multiplexer inputs mode-locking light signals in dual mode into optical fiber connected to base station after multiplexing. Under condition of shared microwave oscillator in frequency being as 1 / N millimeter wave frequency and light signal modulator in same low frequency, the invention generates millimeter wave light source row by using harmonic modulation technique and mode locking dual mode technique. The invention makes cost for generating light signal in millimeter wave decrease greatly.

Description

Technical field:

[0001] The invention belongs to the technical field of optical fiber transmission wireless signal (Radio-on-Fiber, abbreviated as ROF) communication system, and in particular relates to a wavelength division multiplexing millimeter wave light source array of an optical fiber transmission millimeter wave ROF wavelength division multiplexing communication system. Background technique:

[0002] In recent years, Microwave Photonics (abbreviated as MWP) has developed rapidly. Taking advantage of the respective advantages of wireless communication and optical fiber communication, the "mobile ultra-large capacity ultra-high-speed" optical fiber transmission wireless signal (Radio-on-Fiber , abbreviated as ROF) communication system research work is increasingly given great attention. When the wireless signal is a millimeter wave, the ROF communication system is called a millimeter wave ROF communication system.

[0003] The ROF wavelength division multiplexing comm...
