"Vertical Cavity Transistor Laser"
Mong-Kai Wu

This work presents the recent progress of the transistor laser. The transistor laser is a three terminal device which can simultaneously produce electrical and optical signals. Because of the titled charge configuration in base, the device has shown the fast recombination and 20GHz directed modulation bandwidth. With the shrinkage of device dimensions, the vertical cavity transistor laser is expected to have even higher bandwidth, ideal for short distance optical communication.
