CA 2068443

A distributed feedback semiconductor laser is provided whose active medium presents a periodic thickness variation in the direction of light propagation so as to generate a periodic gain variation, while maintaining a constant effective refractive index. The laser has a discrete multi-quantum wire structure. A method of manufacturing such a laser is also described.
