Abstract
We present here the broadband and parametric gain for tellurite/phospho-tellurite optical fiber by carefully engineering the chromatic dispersion for optical parametric amplifier. This optical parametric amplification with broad bandwidth promises significant solutions for wavelength division multiplexing (WDM) and advanced ultrafast optical telecommunication systems. The parametric gain has been obtained with inclusion of higher and even order dispersion parameters in phase-mismatching factor (Δβ). The results have been obtained for step index fiber (SI) and hybrid microstructured optical fiber (HMOF) with engineered chromatic dispersion, having one zero dispersion wavelength (ZDW) and two ZDWs. The HMOF with a core diameter of 1.1 μm and chromatic dispersions having two ZDWs at 1262 and 1559 nm provides broadest parametric gain bandwidth (280 nm). This broad bandwidth advents due to the high nonlinear coefficient of tellurite/phospho-tellurite hybrid microstructured optical fiber. The paper explores variation in dispersion parameters, supercontinuum spectra and bandwidth of the parametric gains for these fibers.
