Celebrating our Sesquicentennial 1867-2017

Professors Nick Holonyak Jr. and Milton Feng invented the first transistor laser, a device that significantly changes the science and technology of lasers and introduces basic changes in the traditional transistor and what is known about its operation. They began discussions on the transistor laser in 2003 and completed the first demonstration in 2004. Their first patent for the transistor laser was filed in February 2005 and issued in 2006.
