More Information
Summary:The present disclosure provides new and innovative VCSEL devices and systems. In an example, a VCSEL device comprises a cavity mirror with a curved mirror surface of a VCSEL and a radius of curvature (ROC) of the curved mirror surface that is anisotropic, wherein the ROC comprises four directions, the four directions being +x, +y, -x, -y, the ROC in at least one direction is in a range greater than a cavity length of the VCSEL and less than a predefined ROC value for a standard beam width (ROCUL), and the ROC in at least one of the other directions is outside the range.
