New hybrid photonic crystal fiber gas sensor with high sensitivity for ammonia gas detection

A new hybrid photonic crystal fiber with circular rings based microstructure core gas sensor has been proposed for detecting ammonia gas at the wavelength of 1.544μm. The finite element method has been used for numerical investigation. According to the results, the relative sensitivity is obtained as high as 70.25% at the wavelength of 1.544μm. Furthermore, high birefringence and effective area are acquired by orders of 1.2410The accepted manuscript in pdf format is listed with the files at the bottom of this page.
