Anti-Resonant Hollow-Core Fiber Sensor With Microchannel Arrays for Fast CO2 Sensing
A fast carbon dioxide (CO2) sensor utilizing an anti-resonant hollow-core fiber with microchannel arrays is demonstrated, where the microchannel arrays along the fiber cladding are precisely fabricated by a femtosecond laser to enhance the internal gas mass transfer rate to speed up the response. We utilized the method...
