Fetah Benabid is an EPSRC Advanced Fellow and Reader. He did his PhD at the University of Western Australia on high precision optical metrology of sapphire-based components for interferometric gravitational wave detectors. He has been at the University of Bath since 2001. He has developed new fabrication techniques for hollow core photonic crystal fibre (HC-PCF), enabling the production of HC-PCF with a very high air-filling fraction whilst keeping its structural integrity.
He has been a pioneer in incorporating these fibres into scientific and technological applications, which includes the demonstration of stimulated Raman scattering (SRS) in hydrogen filled HC-PCF with pump powers one million times lower than those required using conventional techniques. He was at the forefront in demonstrating electromagnetically-induced transparency (EIT) in molecular gases such as acetylene. More recently he has developed a novel technology capable of fabricating compact and all-fibre integrable HC-PCF based gas cells, with which he has demonstrated a number of quantum and nonlinear effects.
His current research activities focus on nonlinear and coherent optics (e.g. EIT and molecular modulation) in gas-phase filled HC-PCFs, and the development of new types of HC-PCFs. In recognition of the significance of his work he was awarded the European Physical Society Fresnel Prize in 2005 "for his pioneering work on the development of hollow core photonic crystal fibres and their application in laser-guidance of particles and ultra-low threshold stimulated Raman scattering in molecular gases".
