QPhotonics is a specialist supplier of semiconductor light emitting devices in wavelength range 405nm-1650nm for research, development, and production. We offer a large variety of laser diodes, superluminescent diodes, and semiconductor optical amplifiers. Individual devices can be selected from stock and purchased online. We also provide controllers, mounts, collimators, and photodiodes for building laser systems.


QPhotonics was established in 2000 by George Loutts, professor of physics at Norfolk State University in Norfolk, Virginia, USA. Until 2007 we have been operating in Chesapeake, Virginia. In August 2007 QPhotonics was moved to Ann Arbor, Michigan. (click here for Contact).

Customer testimonials:
"I have been employing laser diodes from QPhotonics for several years in steady-state and time-resolved luminescence experiments. These laser diodes are rugged, reliable, and very user friendly, which allows me to use them in state-of-the-art research experiments as well as educational projects." Uwe Hommerich, Hampton University, Hampton , Virginia .

”the modules are working perfectly!” Yoel Fink, MIT, Cambridge, Massachusetts.
