Abstract: Cyanide (CN) is a highly toxic chemical agent that is considered extremely harmful to humans. Considering the level of toxicity and harmfulness to human it is important to have an efficient and flexible detection method of CN. Based on this requirement, we propose a photonic crystal fiber (PCF) based terahertz sensor for the detection of CN. In a Zeonex substrate we use symmetrical and asymmetrical core structures inside a suspension type cladding. The possible sensor architecture and methodology of sensing is also addressed. The fabrication of the proposed sensors is feasible employing existing fabrication technology.
