Impact Statement:
Standard circular VCSELs lack in high-power single-mode emission. Our innovative designs targeting patterned large-area rectangular VCSELs offer diverse capabilities, enabling single-mode, single-polarization emissions, uniform current injection, optimized far-field characteristics, and improved thermal management, to be selected depending on the specific requirements. These advancements serve a broad technologist audience, enhancing VCSEL performance across novel applications.
Abstract:
In this work we investigate patterned large-active area AlGaAs vertical-cavity surface-emitting lasers (VCSELs) targeting high-power single-transverse-mode emission. As a first step, our in-house 3D electromagnetic vectorial mode solver VELMS is validated against preliminary experimental data. Then, VELMS is applied to implement single-mode operation on VCSELs featuring large-area rectangular oxide apertures. A comparative appraisal of different mode selection strategies based on patterning the outcoupling facet of the device is presented, providing a number of alternatives for a broad audience of technologists.
