Strain-controlled impurity-induced disordering for apertures in single-mode vertical-cavity surface-emitting lasers
… optical sensors. Through the initiation of Zn diffusion, impurity-induced disordering (IID) has been demonstrated to enable optical mode control, increased modulation frequencies, and provide carrier and photon confinement in vertical-cavity surface-emitting lasers. While disordering …

High-power single-mode vertical-cavity surface-emitting lasers via impurity induced disordering
… method (TMM) is developed to account for the diffusion of Group III atoms of the distributed Bragg reflectors (DBR) that comprise the VCSEL. In addition, a simple fiber model is used to design the transverse profile of the IID regions to maximize single-mode output power. IID VCSELs are …
