A History of the VCSEL

Facebook X LinkedIn Email
Sixty years ago this month, Theodore H. Maiman, a physicist at Hughes Research Laboratories in Malibu, Calif., constructed the first laser using a cylinder of synthetic ruby and photographic flash lamps. There have been many milestones in the last six decades. In honor of this breakthrough, Photonics Media will be running periodic coverage throughout the month.

TOKYO, May 18, 2020 — 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...Read full article
