Abstract

We experimentally investigate low-dimensional VCSEL structures on several epitaxial stacks with and without dielectric gratings, demonstrating mode selectivity enabling single-mode operation. We also develop a finitedifference time domain VCSEL model enabling mode-diverse simulations of dielectric gratings. We correlate experimental and simulation results, demonstrating a pathway toward optimization of grating parameters toward high-power, coherent single mode VCSELs.
