Abstract: (528 Views)
In this paper, a new geometric structure is designed for a photonic crystal fiber as a hydrogen sulfide gas sensor. The PCF-based gas sensors can detect the concentration of chemical material such as hydrogen sulfide. The geometric structure design is such that it enhances the interaction of light and gas in the fiber core and decreases the confinement loss and increases the relative sensitivity of the sensor.
The overall calculation is completed by using a finite element method (FEM) with a perfectly matched layer (PML) boundary condition. The investigated results reveal the relative sensitivity of 47.394% and confinement loss of 1.1×10-5 dB/cm at the 1.55µm wavelength.
