Toward Lasers of the Next Generation
One very feasible nanostructure optical device is a quantum dot (QD) laser. When quantum wire (QWR) and QD lasers were proposed in 1982 , a suppression of the temperature dependence of the threshold current in QWR and QD lasers was discussed theoretically. A significant improvement of lasing characteristics such as a low threshold current, fine modulation dynamics, and good spectral properties were predicted theoretically [2–4]. In this section, we focus on QD lasers with emphasis on lasing characteristics and microcavity effects .
