Top View of the Nanolaser (image) American Institute of Physics Share Print E-Mail Caption This image shows a top view of the group's nanolaser, in which the center narrow slot (horizontal line) is the main part of the sensor. The periodic holes form a photonic crystal, and although the size of the holes appears to fluctuate they've been intentionally modified so the laser's emission is effectively extracted to the top.
