| Popis: | International audience; The authors present a home made cryogenic electro-optical probe station allowing the direct modulation of quantum cascade lasers up to 40GHz. Based on a QMC cryostat, it should make the QCL bandwidth measure possible and then help answering questions about the modulation possibilities of such a kind of laser. The experimental results will be compared to simulation bandwidth prediction based on a complete set of rate equations describing the dynamic behavior of the laser. Bandwidth will be then linked to the different intrinsic and structural parameters. |
