Evaluation scheme for the design of poweroptimized single mode vertical-cavity surfaceemitting lasers.
A very simple and efficient evaluation procedure is suggested for the design of power-optimized single mode VCSELs by reviewing the physical mechanisms that governs mode transition and simplifying the computation steps. In addition, the new structures are proposed and tested following the suggested evaluation procedure. As a result, the proposed design exhibits much better stability of the fundamental mode over a current range wider than the conventional one.
