Fiber Optical Parametric Amplifier

A photonic crystal fiber (PCF) with a zero-dispersion wavelength (ZDW) in the telecommunication region is designed and an ultra-broadband fiber optical parametric amplifier (FOPA) based on such PCF is simulated. Results show that the PCF-based FOPA exhibits much higher gain with a very broad bandwidth (covering O- to U-band) in comparison with the highly nonlinear fiber (HNLF)-based FOPA. Also, the required fiber length and the input pump power are reduced for the PCF-based FOPA. The obtained results show the great potential of the PCF-based OPA for the telecommunication applications, e.g. amplification of wavelength-division multiplexing (WDM) signals.

Influence Of Temperature On

AbstractThis paper describes study of photonic crystal fiber (PCF) in order to study the influence of temperature on the chromatic dispersion; these types of fibers are based on commercial structures, but air holes will be infiltrated with water. Using finite domain-beam propagation method, it is shown that the zero dispersion wavelength can be shifted from 1.058753 to 1.271767 µm, a shift of 213 nm. At 50 °C, a shift of 169 nm.As a result, we reveal that the proposed PCF can successfully compensate for the chromatic dispersion by the influence of temperature. Furthermore, the design model and methodology can be applied to design other dispersion-based devices, such as dispersion-flattened fibers and dispersion-shifted fibers, or can be used also as a sensor of temperature.

We numerically investigate the use of photonic crystal fiber (PCF) through dispersion engineering of its cladding containing air-holes for supercontinuum (SC) generation in the mid-infrared region using low peak power. A 3.6-cm-long PCF made using Ge11.5As24Se64.5 chalcogenide (ChG) glass with a hexagonal array of air-holes was optimized for obtaining zero-dispersion wavelength through dispersion tailoring around the pump wavelength of 4 μm. We have performed numerical simulations for such dispersion tailored ChG PCF with the peak power range between 0.25 kW and 2 kW. It was found through rigorous numerical simulations that an ultrabroadband mid-infrared SC spectra covering the wavelength range 2-8 μm which is equivalent to 2 octaves could be generated using pump pulses of 320 fs duration at a wavelength of 4 μm with a relatively low peak power of 2 kW by using our proposed ChG PCF design.
