Abstract
An optical illuminator using Vertical Cavity Surface Emitting Laser (VCSEL) is disclosed. Optical modules configured using single VCSEL and VCSEL arrays bonded to a thermal submount to conduct heat away from the VCSEL array, are suited for high power and high speed operation. High speed optical modules are configured using single VCSEL or VCSEL arrays connected to a high speed electronic module on a common thermal submount or on a common Printed Circuit Board (PCB) platform including transmission lines. The electronic module provides low inductance current drive and control functions to operate the VCSEL and VCSEL array. VCSEL apertures are designed for a desired beam shape. Additional beam shaping elements are provided for VCSELs or VCSEL arrays, for desired output beam shapes and/or emission patterns. VCSEL arrays may be operated in continuous wave (CW) or pulse operation modes in a programmable fashion using a built-in or an external controller.
