Suspended Ring-Core Photonic Crystal Fiber Gas Sensor With High Sensitivity and Fast Response
IEEE Photonics Journal, 2015 We demonstrate the design and fabrication of an in-line evanescent field gas sensor based on a novel suspended ring-core photonic crystal fiber (PCF) to further overcome limitations in sensing capability.

Golden spiral photonic crystal fiber: polarization and dispersion properties [PDF]
, 2008 A golden spiral photonic crystal fiber (GS-PCF) design is presented in which air holes are arranged in a spiral pattern governed by the golden ratio, where the design has been inspired by the optimal arrangement of seeds found in nature.
