- •
An elliptical-cored HPCF structure is used here to investigate guiding properties.
- •
This research has gained maximum sensitivity and confinement loss at a satisfactory level.
- •
FEM with perfectly matched layer circular boundary has been applied to discover sensitivity and confinement loss.
- •
Higher birefringence is also gained for proposed structure.
- •
Moreover, nonlinear coefficient, effective area, splice loss, V parameters and beat length are examined.
