World around researchers are working to develop nano-optical chips, where light can be controlled. These could be used for future circuits based on light (photons) instead of electrons -- that is photonics instead of electronics. But it has proved to be impossible to achieve perfect photonic nanostructures. Now researchers have shown that imperfect optical chips can be used to produce 'nanolasers',...
