World's smallest microcavity laser for optical computing

From Nanowerk, physicists at ETH-Zurich have developed the smallest electricallyumped laser in the world that could revolutionize chip technology ("Microcavity Laser Oscillating in a Circuit-Based Resonator").

The laser is 30 micrometers long, eight micrometers high and has a wavelength of 200 micrometers. This makes the laser considerably smaller than the wavelength of the light it emits
