HSIC Demonstrates 57 Gbps Error-Free Data Transmission

HSIC graduate researcher Michael Liu presented HSIC’s latest work on state-of-the-art VCSEL technology at the 2016 Optical Fiber Communication Conference and Exhibition (OFC). The work, done in collaboration with Prof. Milton Feng, Prof. Nick Holonyak, Jr., and graduate researcher Curtis Wang, showed record-breaking 57 Gbps error-free data transmission at room temperature and 50 Gbps at 85 degrees Celsius.

Stimulated Photon-Assisted Tunneling in the Transistor Laser

Prof. Milton Feng and graduate students Curtis Wang and Junyi Qiu (pictured) along with Prof. Nick Holonyak, Jr. have discovered the phenomenon of intra-cavity photon-assisted tunneling (ICpaT) in the Transistor Laser. This phenomenon is unique to the Transistor Laser with its three-port structure and electrical/optical ouput, where photon absorption in the collector promotes a very quick tunneling process that serves as a direct-voltage-modulation scheme. Under this scheme, the Transistor Laser can be modulated down to the femtosecond range, much faster than direct-current-modulated diode lasers.

This work is sponsored by the Air Force Office of Scientific Research.
