AbstractIn this paper, the dispersion characteristics of two standard single-mode optical fibers (SMFs), fabricated with silica and poly (methyl methacrylate) (PMMA) are studied in telecommunication spectral regions. The effect of structural parameters, such as the radius of the fiber core and the relative core-cladding index difference, is numerically investigated. It is found that over whole spectral range, the PMMA-based SMF shows lower dispersion than the silica SMF. Also, the zero-dispersion wavelength (ZDW) of PMMA-based SMF is longer than that of silica fiber. The results may be of practical importance for the telecommunication applications.

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.
