    A History of the VCSEL

    Article obtained from Photonics RSS Feed.

    The VCSEL (vertical-cavity surface-emitting laser) was invented in 1977 by Kenichi Iga. VCSELs are used in myriad applications, such as cellphone security, optical communication, computer mice, gas sensing, optical clocks, laser pumping, and others. Iga was awarded the 2013 Franklin Institute Awards’ Bower Award and Prize for Achievement in Science for the conception and development of the VCSEL and its multiple applications in optoelectronics.

    In 1989, Jack Jewell was able to demonstrate over one million VCSELs on a single chip at Bell Laboratories, a feat developed from his doctoral work under Hyatt Gibbs between 1980 and 1984. In that work he used nonlinear optical properties of GaAs to make all-optical logic gates that…
