Core fields in graded fibres with non-circular index contours
Core fields in graded fibres with non-circular index contours
Fields in the cores of graded noncircular optical fibres are analysed using a new method. It is shown that the scalar wave equation in elliptical co-ordinates can be separated for many realistic noncircular profiles, thus allowing calculation of fields by a double WKB method. The boundaries separating oscillatory and evanescent regions are found by simple analysis of algebraic equations. This method supports and further explains previous analysis which used geometric optics.

Abstract
Fields in the cores of graded noncircular optical fibres are analysed using a new method. It is shown that the scalar wave equation in elliptical co-ordinates can be separated for many realistic noncircular profiles, thus allowing calculation of fields by a double WKB method. The boundaries separating oscillatory and evanescent regions are found by simple analysis of algebraic equations. This method supports and further explains previous analysis which used geometric optics.
