Summary:We have noted that for VCSELs at 850 nm, the only LAN standard wavelength where VCSELs have been shown to operate, have thresholds greater than 1.6 volt, so that if it is desirable to operate circuits at lower absolute voltage levels, VCSELs may not be used. However, we have demonstrated a GaAs MQW electro optical modulator that has a contrast of 2:1 at a differential drive of +/- 1.6 volt
