Design flexibility and enormous optical properties of Photonic Crystal Fiber (PCF) suited for different types of applications have influenced researchers and engineers in enhancing present drawbacks. Photonic crystal fiber is based on periodic morphological microstructure of air-holes where different arrangement of air holes led to different types of structures. Several types of structures with different shapes like Hexagonal, Octagonal, Honeycomb, Circular etc. have been proposed earlier. In this research, a novel PCF structure is proposed with butterfly geometry being inspired by natural form of PCF. To validate the performance of the new design, optical properties like dispersion, confinement loss and high nonlinearity are extracted with satisfactory results. COMSOL Multiphysics is used as modelling and simulation environment. To achieve negative dispersion -1.56x10^4 ps/km.nm at 1550nm, holes diameter and their spacing are considered accordingly. Multiple defect holes as well as elliptical core make the structure asymmetric which exhibits high nonlinearity of 42.7WKm at the operating wavelength 1550nm. High nonlinearity with negative dispersion makes the proposed structure suitable for telecommunication applications also in long distance data transmission, super-continuum generation, fiber sensor design and as Dispersion Compensating Fiber (DCF) etc.
