Paper Abstract

We have measured the active region size dependence of the high speed modulation characteristics of vertical cavity surface emitting lasers with lateral current injection. The moveout rate df0d(root)P and K factor determined from a curve fit to the small signal modulation data were df0d(root)P approximately equals 4.5-6.5 GHz/(root)mW and K approximately equals 0.68-0.85 ns for both 10 and 20 micron diameter devices. The maximum resonance frequency was limited by device heating, and a parasitic type of rolloff in the modulation response was observed, which we fit to a diffusion capacitance model.
