Researchers from Japan have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications such as biosensing, displays, healthcare and optical communications.

Long considered a holy grail in the area of light-emitting devices, organic diodes use carbon-based organic to emit light instead of the inorganic semiconductors, such as gallium arsenide and gallium nitride, used in traditional devices.
