The simulation results show the relative sensitivity of 27% and confinement loss of 0.0034 dB/m at λ = 5 μm absorption wavelength of N2O gas. In this design, we consider a spectral band of wavelength from 4.6 μm to 5.6 μm because the absorption wavelength of N2O gas having the value of 5 μm is suitably matched to this range. In addition, highly birefringent HPC-PCF design is more capable for separating the light polarizations and its high numerical aperture allows strong gathering of light into the core, which further reduces the confinement loss. |
