Two Papers by Center for Quantum Devices Investigators Selected for IEEE Journal of Quantum Electronics Cover Stories

Razeghi is the Walter P. Murphy Professor of Electrical and Computer Engineering and director, Center for Quantum Devices. Slivken is a research professor of electrical and computer engineering at the Center for Quantum Devices.
Razeghi and Slivken demonstrated simultaneous room temperature operation and high-power output power, which is a first for this type of laser. The layer sequence and contact geometry exhibit relatively low series resistance and optical losses, through some optimization can still be done at this time.

The paper, titled "Demonstration of Zn-Diffused Planar Long-Wavelength Infrared Photodetector Based on Type-II Superlattice Grown by MBE," demonstrated the world's first planar long-wavelength infrared photodetector based on type-II superlattices.
