In this article, we have presented a new design methodology of obtaining wide band parametric sources based on highly nonlinear chalcogenide material of As2S3. The dispersion profile of the photonic crystal fiber (PCF) has been engineered wisely by reducing the diameter of the second air-hole ring to have a favorable higher order dispersion parameter. The parametric gain dependence upon fiber length, pump power, and different pumping wavelengths has been investigated in detail. Based upon the nonlinear four wave mixing phenomenon, we are able to achieve a wideband parametric amplifier with peak gain of 29 dB with FWHM of ≈2000 nm around the IR wavelength by proper tailoring of the dispersion profile of the PCF with a continuous wave Erbium (Er3+)-doped ZBLAN fiber laser emitting at 2.8 μm as the pump source with an average power of 5 W. The new design methodology will unleash a new dimension to the chalcogenide material based investigation for wavelength translation around IR wavelength band.read more

Ultralow-Power Four-Wave Mixing with Rb in a Hollow-Core Photonic Band-Gap Fiber
TL;DR: This work demonstrates extremely efficient four-wave mixing with gains greater than 100 at microwatt pump powers and signal-to-idler conversion of 50% in Rb vapor confined to a hollow-core photonic band-gap fiber and presents a theoretical model that demonstrates such efficiency is consistent with the dimensions of the fiber and the optical depths attained.

Effect of HOD parameters on gain and bandwidth of parametric amplifiers for near-zero ultra-flat dispersion profile
Rohaan Deb,Partha Sona Maji +1 more
TL;DR: In this article, the performance of FOPA in terms of gain and bandwidth based on the optimized dispersion profile is thoroughly investigated incorporating different higher order dispersion (HOD) parameters, and the spectral shift and width of the additional peaks are found to vary significantly due to the incorporation of these different HOD terms.
