We demonstrate experimentally that mid-infrared quantum cascade lasers(QCLs)operating under external optical feedback exhibit extreme *** events can be triggered by adding small amplitude periodic modulation,with the highest success rate for the case of a pulse-up *** findings broaden the potential applications for QCLs,which have already been proven to be a semiconductor laser of interest for spectroscopic applications and countermeasure *** ability to trigger extreme events paves the way for optical neuron-like systems where information propagates as a result of high intensity bursts.

Free-space optical communication is a very promising alternative to fiber communication systems,in terms of ease of deployment and *** light has several features of utter relevance for free-space applications:low absorption when propagating in the atmosphere even under adverse conditions,robustness of the wavefront during long-distance propagation,and absence of regulations and restrictions for this range of wavelengths.A proof-of-concept of high-speed transmission taking advantage of intersubband devices has recently been demonstrated,but this effort was limited by the short-distance optical path(up to 1 m).In this work,we study the possibility of building a long-range link using unipolar quantum *** different detectors are used:an uncooled quantum cascade detector and a nitrogen-cooled quantum well-infrared *** evaluate the maximum data rate of our link in a back-to-back configuration before adding a Herriott cell to increase the length of the light path up to 31 *** using pulse shaping,pre-and post-processing,we reach a record bitrate of 30 Gbit s−1 for both two-level(OOK)and four-level(PAM-4)modulation schemes for a 31-m propagation link and a bit error rate compatible with error-correction codes.

Space-to-ground high-speed transmission is of utmost importance for the development of a worldwide broadband ***-infrared wavelengths offer numerous advantages for building such a system,spanning from low atmospheric attenuation to eye-safe operation and resistance to inclement weather *** demonstrate a full interband cascade system for high-speed transmission around a wavelength of 4.18μ*** low-power consumption of both the laser and the detector in combination with a large modulation bandwidth and sufficient output power makes this technology ideal for a free-space optical communication *** proof-of-concept experiment employs a radio-frequency optimized Fabry–Perot interband cascade laser and an interband cascade infrared photodetector based on a type-II InAs/GaSb *** bandwidth of the system is evaluated to be around 1.5 *** allows us to achieve data rates of 12 Gbit/s with an on–off keying scheme and 14 Gbit/s with a 4-level pulse amplitude modulation *** quality of the transmission is enhanced by conventional pre-and post-processing in order to be compatible with standard error-code correction.
