All-Fiber CO<sub>2</sub> Sensor Using Hollow Core PCF Operating in the 2 µm Region

A realistic implementation of an all-fiber CO<sub>2</sub> sensor, using 74 cm of hollow core photonic crystal fiber (HC-PCF) as the cavity for light/gas interaction, has been implemented. It is based on CO<sub>2</sub> absorbance in the 2 &#181;m region. The working range...
