| Abstract(in English) | We investigate the linewidth enhancement factor, α of a Fabry-Perot quantum cascade laser by self-mixing interferometry. For the first time, the theoretically predicted characteristic waveform resulting from a small α could be obtained when the optical feedback parameter was greater than one. The shape of this waveform was totally different from that of a conventional distributed-feedback laser diode with a large α. We demonstrate that subband nonparabolicity could be one of the reasons why quantum cascade lasers have a small, but non-zero, α value. |
