COMPARISON OF DISPERSION CHARACTERISTICS OF SOLID-CORE PCFs INFILTRATED WITH PROPANOL AND ETHANOL

In this paper, we propose the solid-core photonic crystal fibers (PCFs) with hexagonal cladding infiltrated with propanol in the air-holes. The dispersion characteristics and zero- dispersion wavelengths of these PCFs have been compared with previous publications and analyzed in detail. By investigating the dependence of the dispersion characteristics on the air-hole diameters, we determine the optimal structures with 1 µm of that. The PCF infiltrated with propanol exhibits flatter and smaller dispersion characteristic and the zero-dispersion wavelength shifted towards a longer wavelength, 24 nm compared with ethanol permeable PCFs [17]. This result shows that structure with a diameter of air-holes by 1µm is suitable for supercontinuum (SC) generation in the near- infrared wavelength range.

Design and analysis of highly nonlinear, low dispersion AlGaAs-based photonic crystal fiber

An AlGaAs based standard photonic crystal fiber structure is reported for low dispersive nonlinear optics applications. By employing a finite element solver with perfectly matched layer boundary condition, the key propagation characteristics are investigated over a broad wavelength span (1–5 μm) by taking the different air filling fraction values. The proposed work provides an effective fundamental mode area of 7.30 μm2 with nonlinearity in the order of 8.325 W−1m−1 at a low absorption wavelength of 1.55 μm and zero-dispersion wavelength close to 3 μm.
