abstract = "In this work, we investigate data transmission in the long wavelength infrared spectrum employing a directly-modulated quantum cascade laser and a quantum cascade detector in ridge architecture, both operating at a wavelength around 9 µm. We were able to measure bit rates of 200 Mbps for a two-level (OOK) modulation scheme in a back-to-back configuration at room temperature. The findings of this study pave the way for further development of these devices to be employed in integrated photonic circuits for advanced applications in secure and high-speed free-space optical communications.",
