Propagation characteristics of an elliptical hollow core optical fiber (EHOF) have been investigated under the application of high lateral and hydrostatic stresses. The simulation results exhibit significant effects of stress on birefringence, polarization mode dispersion (PMD), group velocity dispersion, effective area, and power confinement. High birefringence (~10−3), negative dispersion (−22.07 ps/km-nm), low PMD, small effective area, and ultrahigh value of power density (~103) have been found for EHOF under different stresses. The inclusion of central air hole and asymmetry in geometrical structure of the fiber under stress are responsible for different changes in propagation characteristics.
