850nm Oxide-Confined VCSEL with 40 Gb/s Error Free Data Transmission

Congratulations to Dr. Fei Tan, Mong-Kai Wu, and Michael Liu for their spectacular efforts in developing an oxide-confined VCSEL that can transmit 40 Gb/s error free data rate. This device is the fastest directly modulated laser (not using a peaked driver circuit) in the United States

850 VCSEL.
