Novel photonic devices thanks to loss and gain interplay

Contrary to common sense, optical loss may not be detrimental to laser operation. New results demonstrate that optical loss and laser gain can work together, pointing to high-compact and more efficient lasers.

Photonic media with gain and loss offer exciting potential for the control of electromagnetic radiation in micro and nanolasers. Scientists initiated the NOLACOME (Nonlinear optics and lasing in complex media) project to conduct a detailed theoretical exploration of important related topics.
