Multichannel homodyne detection for quantum optical tomography
Georgios Roumpos, Steven T. Cundiff · Journal of the Optical Society of America B · 2013
We present a multichannel optical homodyne detection setup suitable for measurements of quantum light statistics with ultrafast time resolution. We employ the setup to measure light statistics of diode lasers driven by both a direct and a pulsed current source. In particular, we measure the time-resolved second-order correlation function g(2) and photon number distribution. Our results provide information about the dynamics of the lasing transition.
