This paper presents the design and analysis of elliptical photonic crystal fibers (EPCFs) optimized for sensing applications in the near-infrared (NIR) region. The unique geometry of EPCFs, characterized by elliptical air holes arranged in a periodic lattice, offers enhanced sensitivity and tunable optical properties compared to conventional circular photonic crystal fibers. The proposed EPCF design focuses on achieving high birefringence, low confinement loss, and optimized dispersion properties, making it suitable for a wide range of sensing applications, including biochemical and environmental monitoring. The simulation results demonstrate that the EPCF exhibits significant birefringence, which enhances its sensitivity to changes in the external refractive index, a crucial parameter for effective sensing. Additionally, the low confinement loss ensures efficient light propagation through the fiber, while the tailored dispersion profile minimizes pulse broadening, thereby improving the accuracy and reliability of the sensing measurements. The findings provide valuable insights into the design principles and optimization strategies for developing advanced fiber-based sensors with superior performance in detecting and monitoring various physical, chemical, and biological parameters.
