Abstract
Injection locking dramatically modifies the phase and transverse outpu t 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 different methods: insertion of a heli coidal phase mask, interference of two Gaussian beams, and injection l ocking of the TEM(01) and TEM(01) modes of a VCSEL to form the TEM(01 ) donut mode. The first two methods stem from geometrical optics; the third method involves nonlinear mode competition in the laser cavity.
