Millimetre-wave signal generation using FWM effect in SOA

Advances in Optical Amplifiers

“…use the SOA-MZI (semiconductor optical amplifier Mach-Zehnder interferometer) to realize frequency up conversion to mm -wave, this just use the XPM effect in the SOA to generate the mm-wave. Many researchers preferred to use the FWM to generate mm-wave [6,[56][57][58][59][60].The reason is we can get cost-effective mm-wave by using FWM effect compared with other two nonlinear effects of high nonlinear medium. In 2006, J.…”

The Application of Semiconductor Optical Amplifiers in All-Optical Wavelength Conversion and Radio Over Fiber Systems

“…suggested to use SOA instead of HNLF, and the pump are also two phase-locked generated by OCS intensity modulation [57].Then S. Xie etc. also proposal some scheme based on FWM effect of SOA to generate mm-wave [58][59][60].In Ref. [58], they use two cascaded optical modulators and FWM effect in SOA to generate a 12 times microwave source frequency with high spectral purity.…”

Optical millimeter-wave generation utilizing optical parametric loop mirror and fiber Bragg grating

“…Because of only one light source used, the coherence among all frequency components is satisfied. There are several solutions for creating optical harmonic components, such as overdriving an electrooptic modulator (intensity or phase modulator) using a microwave signal with amplitude much higher than V π [5]; FWM in fiber [6] or SOA [7] and so on. FWM is a successful way to generate harmonic frequency, which has been shown in several pervious works [6].…”
