Semiconductor Quantum Dots for Optoelectronic Applications

The early predictions and investigations of the optical properties of semiconductor quantum dots (QDs) focused on the improvement of already known semiconductor lasers and amplifiers by the use of low-dimensional active regions [1, 2]. Today the scope has broadened to include quantum computing [3], biophysics [4], efficient switching nodes [5], single photon emitters [6], widely tunable lasers [7], receivers and detectors of electromagnetic signals in the far infrared regime [8], and new emitters for the access and metro markets [9, 10]. This development has been driven by the desire to understand the new physics of QDs and QD-devices compared with the previously known opto-electronic semiconductor devices.
