30 Gb/s directly modulated 850 nm datacom VCSELs

Abstract

Error free data transmission at 30 Gb/s has been demonstrated using a 6 micron oxide aperture AlGaAs based VCSEL with GaAs quantum wells and conductive AlGaAs mirrors operating at 850nm. This is comparable to the best results for VCSELs at any wavelength to date. The devices were grown using MBE and processed using the standard Advanced Optical Components process. The design methodology used a combination of 1D and 2D optical, and electrical simulations to minimize absorption and resistance simultaneously as well as to optimize speed. © 2008 Optical Society of America.
