Monolithic, Electronically and Widely Tunable Quantum Cascade Laser Sources

Eos Photonics, in collaboration with the group of Prof. Loncar at Harvard University, proposes to further develop a novel widely tunable, high power quantum cascade laser source for remote sensing applications. Eos will then transition this revolutionary mid-IR laser into a commercial product that is ideally suited for the standoff detection and identification of threats such as explosives and chemical warfare agents. The tuning mechanism of our source is fully electronic and uses no moving parts, relying instead on the integration of intersubband tuning elements fabricated monolithically with DBR gratings to ensure electrically-controlled wavelength tuning over a wide wavelength range and with excellent mode suppression ratio.
