Abstract

A VCSEL illuminator module includes a module forming a physical cavity having electrical contacts positioned on an inner surface of the module that feed through the module to electrical contacts positioned on an outer surface of the module. A VCSEL device is positioned on the inner surface module and includes electrical contacts that are electrically connected to the electrical contacts on the inner surface of the module. The VCSEL device generates an optical beam when current is applied to the electrical contacts. An optical element is positioned adjacent to an emitting surface of the VCSEL device and is configured to modify the optical beam generated by the VCSEL device.
