Semiconductor quantum dots

The self-assembly technique of semiconductor quantum-dot structures provided a breakthrough in the development of quantum-dot lasers. Although several properties make quantum-dot structures very interesting for several smaller scale applications, one can expect a strong extension to further areas by tailoring the dot structures in a way to realize specific device properties in the future. With this technique, it should be possible to realize gain material with temperature-stable emission wavelengths suitable for uncooled laser applications or broad-gain multiwavelength amplifications in next-generation semiconductor optical amplifiers (SOAs).
