Paper Abstract

The time evolution of the first three higher order transverse modes is studied for proton-implanted VCSELs using a spatially resolved multi-mode rate equation model. The cylindrically symmetrical model includes spatial hole burning, thermal lensing, current spreading, carrier diffusion and gain saturation. This role of thermal effects and gain non- linearity are studied for transverse mode competition in proton-implanted VCSELs by operating the device with long electrical pulses. Limitations in the single mode operation resulting from the spatial hole burning and thermal effects are observed.
