A light-emitting diode in which there is stimulated emission with amplification but insufficient feedback for oscillations to build up to achieve lasing action.

In a gain medium, amplification of spontaneously emitted radiation characterized by moderate spectral line narrowing and moderate directionality.
Note: Superradiance is usually distinguished from lasing action by the absence of positive feedback, and hence the absence of well-defined modes of oscillation.
