Two-photon photovoltaic effect in gallium arsenide
Abbreviated Journal Title
NONLINEAR ABSORPTION; SILICON; GAAS; Optics
The two-photon photovoltaic effect is demonstrated in gallium arsenide at 976 and 1550 nm wavelengths. A waveguide-photodiode biased in its fourth quadrant harvests electrical power from the optical energy lost to two-photon absorption. The experimental results are in good agreement with simulations based on nonlinear wave propagation in waveguides and the drift-diffusion model of carrier transport in semiconductors. Power efficiency of up to 8% is theoretically predicted in optimized devices. (C) 2014 Optical Society of America
