An analytical expression for mode-conversion coefficients at a laser–air interface is derived using plane-wave decomposition of the modal fields. Both the mode-conversion coefficients and the radiation pattern are explicitly expressed as function of Fresnel reflection coefficients of the interface and the incident mode spectrum. © 1986 Optical Society of America.

Plane-wave-spectrum approach for calculations of radiation pattern of junction lasers

Journal of the Optical Society of America A: Optics and Image Science, and Vision

We present the studies of the modes of a uniaxially anisotropic linear guide by a plane-wave spectrum approach. Starting with an arbitrary optical axis, the axial phase constants of the modes are evaluated for special cases. We conclude with the determination of Green’s function for Eymn and Exmn modes of the guide. © 1990 Optical Society of America.

Greenâ€™s function of a linear anisotropic dielectric guide with a misaligned optic axis

The application of the plane-wave-spectrum method to strip–slab waveguides is described. The dispersion equation of the structure is first evaluated from the condition of self-consistency of rays. By treating the modes as the superpositions of plane waves, Green’s function for the structure is subsequently derived. © 1987 Optical Society of America.
