Injection locking dramatically modifies the phase and transverse output intensity profile of vertical-cavity surface-emitting lasers (VCSELs). Injection can induce a VCSEL to emit a high-order transverse mode. Vortices are generated by three differen

Coherent energy transfer gives rise to a new peak and dip in the probe gain spectrum that moveproportionally with the mtracavity injected power, showing that stimulated emission and absorptionsignificantly speed up the semiconductor response.1. INTRO

Self-focusing leads to bifurcations of transverse solitary waves in sodium vapor (2D) and to second-order spatial solitons in a GaAs planar waveguide gain medium (1D). Transverse patterns in vertical-cavity surface-emitting lasers are shown to contai

Injection of a cw narrow-band laser beam into a lasing vertical- cavity surface-emitting laser results in the appearance of new frequencies on the way to injection locking as predicted by our theoretical model. Injection also causes a local asymmetri

We summarize our ultrafast switching results in GaAs multiple quantum well directional couplers and report on coherent pulse propagation in single strip-loaded GaAs multiple quantum well waveguides. The transmitted pulse shape is measured by sum freq
