The emergence of photonics, where light rather than electricity is manipulated, is posed to further advance the Information Age. Central to the photonic revolution is the development of miniature laser sources. This presentation will review vertical cavity surface emitting lasers (VCSELs) which have been deployed by the billions for optical interconnect and sensing applications. We describe new microcavity lasers with enhanced performance for the next generation of digital communication applications, as well as coherently coupled VCSEL arrays which are viable candidates for high radiance and optical beam steering applications. Both the modulation and beam steering applications for coherent VCSEL arrays are based on novel microcavity phenomena. We show the optical interaction is based on a temporal phase shift between array elements at the quantum well active region which enables record high bandwidth modulation and phase sensitivity to current injection.
