Tomas Sarmiento

Research Interests

I am now a postdoctoral scholar in the Nanoscale and Quantum Photonics Laboratory.

During my Ph.D. I worked on the developement of 1550 nm dilute-nitride GaInNAsSb/GaAs lasers and on the realization of room-temperature CW 1550nm GaInNAsSb/GaAs vertical-cavity surface-emitting lasers.
