Abstract
Geometric anisotropy in the oxide aperture shape of a VCSEL causes spectral splitting between the otherwise degenerate higher order TEM01 and TEM10 mo des. For a given aperture thickness, the degree of splitting is dependent o n the aperture aspect ratio and average size. This splitting can be calcula ted using a scalar variational method.
