Abstract
A VCSEL device having a mesa for generating laser light includes a centralized thermal containment area and a thermal discharge area surrounding the centralized thermal containment area. The device includes a thermal lensing structure for enhancing or controlling heat flow within the centralized thermal containment area and the thermal discharge area and creating and maintaining an index of refraction between the centralized thermal containment area and the thermal discharge area. The VCSEL device operates as a multimode device when driven at a first current in a continuous wave and the VCSEL device operates as a single mode device when driven at a second current at a pulse rate shorter than an overall thermal time constant of the VCSEL device.
