Samenvatting

The invention concerns a superluminescent light emitting diode (SLED) comprising a semiconductor heterostructure forming a PN junction and a waveguide. The semiconductor heterostructure includes a gain region with a contact means for biasing the PN junction so as to produce light emission including stimulated emission from an active zone of the gain region, and in the active zone a plurality of quantum dot layers, each quantum dot layer made up of a plurality of quantum dots and a plurality of adjoining layers, each adjoining layer adjacent to one of said quantum dot layers. The material composition or a deposition parameter of at least two adjoining layers is different. This ensures an enhanced emission spectral width.
