Femtosecond optical-pulse-induced absorption and refractive-index changes in GaAs in the midinfrared
Publikováno v:
Physical Review B. 60:8890-8896
We report on measurements of the ultrafast changes in the absorption and refractive index of pure GaAs in the near-infrared and midinfrared ranges of the optical spectrum. The multicolor experiments have been performed by using an ultrafast optical p

We report the switch-off and recovery dynamics of a vertical-cavity surface-emitting semiconductor laser induced by injection of near-infrared or midinfrared femtosecond optical pulses. The laser is switched off by carrier-density depletion or carrie

Ultrafast relaxation dynamics of light and heavy holes in GaAs following femtosecond valence-to-conduction-band excitation are measured by probing the light- and heavy-to-split-off hole transitions at different midinfrared wavelengths using the recen

The rates of photoinduced electron transfer from p-InP to Fe(CN)64-/3- acceptors in aqueous electrolyte have been determined as a function of the initial potential drop (Le., band bending ( VBO)) in the semiconductor space charge layer using femtosec
