In this article, an octagonal photonic crystal fiber for ethanol detection is suggested. Birefringence, confinement loss, and relative sensitivity have been explored theoretically. The numerical investigation is done utilizing the finite element method (FEM). It is discovered that the existence of elliptical holes in the center region leads to high values of birefringence along with low confinement loss and high sensitivity. Our study shows that at a wavelength of 1.33 μm, the birefringence, relative sensitivity, and confinement loss of the suggested PCF are 0.0016, 57.91%, and \( 1.6 \times 10^{ - 3} \) dB per m, respectively.
