摘要：

The high-speed direct modulation response of mid-infrared quantum cascade (QC) lasers is investigated up ro a frequency of 2GHz, showing high-frequency data transmission capabilities. The application uf QC lasers to optical wireless communications is discussed and demonstrated in a free-space television link over a distance of 70m.
