摘要：
The linearly polarised (LP) modes in elliptical-core fibre have been analysed theoretically. It was found that the electromagnetic fields of the LP modes in elliptical-core fibre can be expressed as a combination of Mathieu and modified Mathieu functions. The modal characteristic equations and propagation constants are derived. The cutoff frequencies of several lower order modes have been calculated and their propagation characteristics plotted. The effects of core ellipticity on the modal cutoff values and mode transmissions are addressed.
