Design and Study of a Novel Regular Decagon Multilayer Photonic Crystal Fiber

Abstract

This study introduces a unique regular decagon multilayer photonic crystal fiber and investigates its design and properties. Through extensive utilization of COMSOL Multiphysics optical module, the fiber's optical characteristics were thoroughly examined. The simulation outcomes indicate that, within the wavelength range of 1000-1500 nm, the photonic crystal fiber exhibits an effective mode field area ranging from 2.33*10-11 to 2.55*10-11 m2, a nonlinear coefficient between 4.96*10-3 and 8.08*10-3 s³/(kg·m³), a dispersion spanning from 1.46 to 1.54, and a loss varying from 3.76*10-3 to 1.29*10-2. This research presents novel approaches and concepts for the calculation, optimization, and design of photonic crystal fibers, ultimately fostering advancements in optical communication, optical sensing, and related domains. Furthermore, it bears significant implications for the practical implementation of innovative photonic crystal fibers in optical sensing and detection applications.
