Seminar on Quantum Dot Laser

Quantum Dot Laser is a good topic for Electrical and Electronics Students to make their seminar. Quantum dots (QDs) are small conductive regions in a semiconductor containing a variable number of charge carriers( from one to thousand) that occupy well—defined discrete quantum states.Use this for your reference and study purpose only.

Since the 1994 demonstration of a QD semiconductor laser, the research progress in developing lasers based on QDs has been impressive. Because of their fundamentally different physics that stem from zero-dimensional electronic states, QD lasers now surpass the established planar quantum well laser technology in several respects. These include their minimum threshold current density, the threshold dependence on temperature, slightly larger wall-plug efficiency, and range of wavelength obtainable in given strained layer material systems.
