Abstract
Coupling characteristics of a fibre-optic polarization beam splitter c onsisting of two highly elliptic cores are obtained using a rectangula r-core waveguide model. Theoretical results are found to be consistent with the available experimental results. The study indicates that the polorization splitting beat length L(B) decreases with increasing cor e-ellipticity, core-cladding index difference and operating wavelength . Further, for a given core-ellipticity L(B) attains a minimum value w hen the centre-to centre separation between the two cores is about thr ee times that of their semi-minor axis.
