Nanophotonics Laboratory

A 480 sqr. ft. Photonics Laboratory under the direction of Dr. Wan Kuang was set up in 2006. It provides capabilities for optical measurements on components and subsystems. In Fall 2009, Dr. Kuang and his colleagues were awarded an NSF MRI for the acquisition of Vis-NIR Tunable Femtosecond Mode-Locked Laser System for nanophotonic devices and materials research. In January 2010, the new laser and the Photonics Laboratory was moved to a new 624 sq. ft. state-of-the-art room constructed as a low noise environment. Simulations are performed using available software developed in-house and on commercial software.

Equipment and Software

  • Several single frequency continuous wave (CW) diode lasers are
    available at wavelengths of 630, 730, 850, 980, 1310, and 1550 nm.
