Electrically Induced Two-Photon Transparency in Semiconductor Quantum Wells
Alex Hayat, Amir Nevet, Meir Orenstein · Physical Review Letters · 2009
We demonstrate experimentally two-photon transparency, achieved by current injection into a semiconductor quantum-well structure which exhibits two-photon emission. The two-photon induced luminescence is progressively reduced by the injected current, reaching the point of two-photon transparency-a necessary condition for semiconductor two-photon gain and lasing. These results agree with our calculations.
