Abstract :
We have demonstrated that the use of a curved waveguide in an index guided laser can suppress the onset of higher order modes, while having minimal impact on the device performance. While the concept has been demonstrated here in a buried ridge laser fabricated by selective area epitaxy, it applies generally to all types of single lateral mode index guided lasers
