Abstract

Spatially-resolved hot luminescence spectra have been measured from bulk InAs and InSb at room temperature with a femtosecond Ti:Sapphire laser (λ=780 nm) and an optical microscope. The Stokes and anti-Stokes luminescence intensities and their spatial extent exhibited a large, nonlinear laser-power dependence. The luminescence spatial (surface) extent was several times larger than the size of the laser spot (∼2 μm) on the sample. Surprisingly strong anti-Stokes luminescence for InAs was found even down to 400 nm. The anti-Stokes spectrum displayed an interference-like periodic intensity variation, which might imply that a bleached layer was generated by the intense laser beam.
