Detuning characteristics of the linewidth enhancement factor of a midinfrared quantum cascade laser
Naoki Kumazaki, Yohei Takagi, Mikito Ishihara, Kenichi Kasahara, Atsushi Sugiyama et al.
The linewidth enhancement factor of a 5 [mu]m distributed feedback (DFB) quantum cascade laser above the threshold current detuned from the gain peak was investigated. This laser oscillates in two DFB modes located on either side of the gain peak. Using the optical feedback self-mixing method, we h ... [Appl. Phys.
