Scientists at Sensorium Technological Laboratories have presented groundbreaking evidence supporting a novel mechanism for the electrical generation of mid-infrared light.
The electrical generation of mid-infrared light, a spectrum commonly associated with thermal imaging, poses significant technological challenges. While quantum cascade emitters are a mature solution, their reliance on complex band-engineering limits their practicality for consumer applications. As a result, many industries are forced to depend on low-power, incoherent, and inefficient thermal emitters to meet the demands of this critical spectral region, which has applications in security, defense, and healthcare.
Sensorium's scientists have been pioneering research on a new mechanism for direct electricity-to-mid-infrared light conversion. In their latest theoretical study, titled "Nonequilibrium Electrical Generation of Surface Phonon Polaritons" and recently published in Physical Review Applied, the team has taken a significant step forward toward realizing a practical device.
Using an advanced nonequilibrium Green’s function approach, the Sensorium’s team managed for the first time to simulate the energy conversion dynamics at the electronic level, demonstrating its suitability for practical mid-infrared light emitting devices.
The study was conducted in collaboration with researchers from Vanderbilt University, the University of Southampton, and the CNR Istituto di Fotonica e Nanotecnologie.
