Top grating index-coupled distributed feedback quantum cascade lasers
M. Carras, M. Garcia, X. Marcadet, O. Parillaud, A. De Rossi et al.
We report on the modeling and design of top grating distributed feedback (DFB) quantum cascade lasers (QCLs). A low loss, index-coupled, DFB design that is very robust against technological spreads is proposed. Strong DFB coupling conditions are obtained while maintaining a high laser output power. ...
