Based on the cylindrical ¨ector wa¨e functions, the propagation of a wa¨e in a circular wa¨eguide filled with a uniaxial chiral medium is rigorously formulated. By ignoring the diffraction effects of the edge and using the Stratton᎐Chu formula, radiation from an open-end guide is numerically compute

Taking the symmetric slab wa¨eguide as an example, we show that radiation modes of a weakly guiding planar optical wa¨eguide can be approximated by the free-space modes; their field expressions and normalization constants are simple and physically understandable, and can be obtained directly without
