GaAsSb/GaAs 1.3-/spl mu/m-VCSELs for 10 G-bit Ethernet

We demonstrated high-performance GaAsSb VCSELs emitting at 1.295 /spl mu/m with a low threshold current of 1.1 mA and a maximum cw operating temperature of 70 C. After the high-frequency modulation characteristics have been validated, the GaAsSb VCSELs should be viable low-cost light sources for high bandwidth fiber communications.
