Abstract

Summary form only given. We report data taken with optically pumped VCSELs on picosecond timescales, with time resolution given by the pulse duration of our reference pulse (300 fs). The data were obtained using DC balanced homodyne detection which provides average intensity, intensity noise strength, and two-mode intensity correlations. We present data taken with a VCSEL based on two 8.5 nm In/sub 0.04/Ga/sub 0.96/As quantum wells cooled to 10 K. We show how spin-flip processes can populate one electron-hole spin population when only the other spin was initially populated by the pump.
