Golden ratio is often denoted by the Greek letter, usually in lower case, Phi (ϕ) which is an irrational mathematical constant, approximately 1.6180339887. Because of its unique and interesting properties, many mathematicians as well as renaissance artists and architects studied, documented and employed golden section proportions in remarkable works of sculpture, painting and architecture.

In this paper, we have proposed a novel nanophotonic device for nonlinear applications in the visible range. The proposed device is a photonic crystal fiber nanowire composed of highly transparent silica with a germania doped silica as core material. Numerical analysis has confirmed that the proposed nonlinear device has a maximum Raman gain coefficient of 1324 W-1km-1 with a nonlinearity parameter...
