**Quantum Cascade Lasers**

by Vasilios N. Stavrou (ed.)

**Publisher**: InTech 2017**ISBN-13**: 9789535130628**Number of pages**: 116

**Description**:

The calculations on the band structure of cascade lasers and on the electronic band structure of QCL under the existence of an applied electric field are presented. A detailed investigation of electrical and optoelectronic properties of multiple-quantum-well structure is carried out. A theoretical study on the intensity noise characteristics of quantum-cascade lasers under the external noncoherent optical injection is carried out.
