“Lasers are an unseen backbone of modern society. They’re integral to technologies ranging from high-speed Internet services to Blu-ray players.
Physicist Na Young Kim, at the optical bench, is a member of the international team that has demonstrated a revolutionary electrically driven polariton laser that could significantly improve the efficiency of lasers.
The physics powering lasers, however, has remained relatively unchanged through 50 years of use. Now, an international research team led by Stanford’s Yoshihisa Yamamoto, a professor of electrical engineering and of applied physics, has demonstrated a revolutionary electrically driven polariton laser that could significantly improve the efficiency of lasers.
The system makes use of the unique physical properties of bosons, subatomic particles that scientists have attempted to incorporate into lasers for decades.
‘We’ve solidified our physical understanding, and now it’s time we think about how to put these lasers into practice, said physicist Na Young Kim, a member of the Stanford team. ‘This is an exciting era to imagine how this new physics can lead to novel engineering.’
This is truly revolutionary. See the full article here.
Leland and Jane Stanford founded the University to “promote the public welfare by exercising an influence on behalf of humanity and civilization.” Stanford opened its doors in 1891, and more than a century later, it remains dedicated to finding solutions to the great challenges of the day and to preparing our students for leadership in today’s complex world. Stanford, is an American private research university located in Stanford, California on an 8,180-acre (3,310 ha) campus near Palo Alto. Since 1952, more than 54 Stanford faculty, staff, and alumni have won the Nobel Prize, including 19 current faculty members
