It is shown that the multimode behavior can be controlled by changing the relative sizes of the current confinement aperture and the index-guide aperture. This is true even in the limit of devices with very large apertures, for which the cold-cavity resonant wave-lengths and losses are the same for all modes. This concept is used to design optimized structures for high-power single-mode operation.
