Tiny Laser Borrows Principles from Electronics
A Swiss team has built a microlaser that, scaled to the operating wavelength, is the smallest electrically pumped laser yet made.
The microlaser’s core is the electrical resonator, which consists of two semicircular capacitors connected by a coil. In this scanning electron microscope image, the color intensity represents the strength of the electric field; the color itself, current polarity.
