A low loss mechanical splice for gas sensing using Hollow-Core Photonic Crystal Fibre

A Gas Cell Based on Hollow-Core Photonic Crystal Fiber (PCF) and Its Application for the Detection of Greenhouse Gas (GHG): Nitrous Oxide (N2O)

“…In [40][41][42][43], the dynamics of gas flow in PCF, which determine the filling and evacuation time for the PCF-based gas cell, have been investigated. In order to reduce the filling and evacuation time and thus increase the response time of the detection system, researchers used a number of techniques, such as splicing the PCF to a normal single-mode fiber and allowing the gas sample to fill the core at a higher pressure [28], drilling holes on the surface of PCF so that gas can diffuse faster [44][45][46], using specially designed mechanical splices [47,48], and finally using a specially designed fiber [49]. It is important to note that the commercially available gas cell based on PCF does not allow one to change the fiber if required.…”

Research on multi-component gas optical detection system based on conjugated interferometer

“…The multi-component gas detection has played a significant role in many fields, such as in the atmospheric condition detection, the safe operation of the transformer, industrial process control, and medical diagnosis [1][2][3]. The optical gas detection technology based on Beer-Lambert's law is widely applied in detecting different kind of gases such as carbon monoxide, carbon dioxide, methane, hydrogen, and acetylene.…”

Performance Simulation of Hollow-Core Photonic Crystal Fibre as a Gas Sensor for Industry Applications

“…They offer fast response, immunity to electromagnetic interference, high sensitivity, safe from combustion and explosion, lightweight, small size, high-temperature performance, flexible in design and usable in the hazardous environment [14,34].…”
