Paper Abstract

We performed femtosecond two-beam self-diffracted four-wave mixing (FWM) experiment[1,2] in 350 μm undoped and n-type InP at 10 K using a self-modelocked Ti:sapphire laser under below the band gap excitation condition where no absorption occurs. We found strong FWM signal even though no real population is created. Fig. 1 shows the spectrally resolved (SR) FWM signal for 350 μm undoped (a) and n-type (b) at below the band gap of 1.3328 eV (approximate band gap of an undoped InP is 1.41 eV) as a function of time delay T. The excitation laser spectrum is shown as broken line.
