Microwave Signal Mixing by Using a Fiber-Based Optoelectronic Oscillator for Wavelength Division Multiplexed (WDM) Systems
نویسندگان
چکیده
We report on microwave signal-mixing functionality for a fiber-based optoelectronic oscillator. Two wavelength division multiplexed (WDM) channels carrying RF signals at 1320 and 1312 nm are simultaneously upconverted/downconverted by the fiber-based optoelectronic oscillator. The conversion efficiency is found to be approximately −8 dB, and the incoming signals have no effects on the local oscillator spectral purity. This new functionality may be useful in fiber-fed phased-array antenna systems and hybrid WDM/subcarrier multiplexed (SCM) communications systems.

Suppression of Four Wave Mixing Based on the Pairing Combinations of Differently Linear-Polarized Optical Signals in WDM System
Data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (WDM) technology. The combination of four waves (FWM) is a non-linear effect in the wavelength division multiplex (WDM), when more than two wavelengths of light in a fiber launch will occur. FWM amount depends on the channel, the channel spaci...
