This paper reviews our recent progress in the design, fabrication, and performance of Vertical Cavity Surface Emitting Laser (VCSEL) devices and arrays. High power (> 11 mW cw), high speed (10 GHz), high temperature (> 130 degree(s)C) and low voltage (< 2 V) and low threshold current operation are demonstrated. A monolithic spatial filtering technique is implemented for transverse mode control resulting in exceptional optical characteristics. Novel high power 2D coherently-coupled VCSEL arrays emitting over 1 W are discussed. One and two-dimensional individually- and matrix-addressable arrays are demonstrated.
