AXT Emits VCSEL
The 850 nm devices have been successfully modulated at data-rates in excess of 3.125 Gbps with typical power output of 1.0mW and peak power output exceeding 5.5mW. The oxide VCSELs are highly efficient, with output slope efficiencies of 0.45-0.50 Watt/Amp obtained. Devices are available immediately in production volumes, and can be tailored to meet a variety of customer specific product designs.
"This is yet another milestone for our VCSEL Technologies division," said Morris Young, CEO of AXT. "We have steadily increased the data transmission rates for our VCSEL products over the past few months. Because oxide devices can operate at higher speeds than a traditional implanted device, we are now able to satisfy our customers' demands for higher speed VCSEL products."
