Purpose and goal
Fabricate quantum cascade lasers with short wavelengths.
Expected results and effects
Quantum cascade lasers at 1.55 µm would be superior to existing telecommunication lasers. Three effects will be studied: single and double barrier behaviour, the quantum cascade principle and the full laser structure.
Planned approach and implementation
The plan is to fabricate the laser in two main steps. First a long wavelength device and then focus on shorter wavelengths. The following issues will be specifically studied: substrate and epitaxial growth, theory and modelling and finally processing and device evaluation.
