Sub parts-per-billion detection of ethane in a 30-meters long mid-IR Antiresonant Hollow-Core Fiber

Piotr Jaworski et al.

Summary: This work demonstrates the first gas sensor utilizing Wavelength Modulation Spectroscopy technique and a mid-IR guiding Antiresonant Hollow-Core Fiber. By exploiting the unique guidance properties of the ARHCF, the sensor achieved low-volume, high-sensitivity gas detection, showing potential for novel, compact, and reliable gas detectors with precise analysis capabilities.

Hazardous Gas Detection by Cavity-Enhanced Raman Spectroscopy for Environmental Safety Monitoring

Pinyi Wang et al.

Summary: The efficiency of cavity-enhanced Raman spectroscopy (CERS) was demonstrated with a folded multipass cavity for detecting hazardous gases in the atmosphere. By optimizing the number of intracavity beams and designing cavity parameters, ppb-level Raman gas sensing for various explosive and toxic gases was achieved at atmospheric pressure within a short exposure time. The CERS apparatus offers simultaneous detection of multiple gases with ultrahigh sensitivity and selectivity, showing great potential for environmental safety monitoring.

Dynamics of Trace Methane Diffusion/Flow Into Hollow Core Fiber Using Laser Absorption Spectroscopy

William A. Challener et al.

Summary: This study introduces a technique for measuring the flow and diffusion rates of trace gases in atmosphere through hollow core fiber (HCF) using tunable diode laser absorption spectroscopy (TDLAS). The results show that simple equations can be used to measure diffusion and pressure-induced flow through the fiber end faces, and the data are in excellent agreement with the theory. Additionally, it is found that highly sensitive trace gas concentration measurements can be achieved using short lengths of HCF filled with external gas samples within minutes or even seconds, which is critical for remote trace gas sensing.

Gas-induced differential refractive index enhanced guidance in hollow-core optical fibers

T. W. Kelly et al.

Summary: Hollow-core fibers (HCFs) with glass membranes defining a hollow core can have their optical properties dramatically changed, including loss, bend loss, and modality, by introducing an extremely small gas-induced differential refractive index (GDRI). This provides a new means to control the optical properties of HCF post-fabrication, enhance their performance, and open up new design possibilities.
