Abstract :
Summary from only given. We have studied single and multimode oxide confined VCSELs with emission wavelength 850 nm at 10 Gbit/s current modulation. The VCSEL structure is schematically shown. Simulations have been performed using a new comprehensive model, which includes the detailed geometry and layer structure and takes into account the effects of carrier density and temperature on the dynamic evolution of the optical field distributions.
