Unipolar quantum cascade lasers (QCLs) utilizing intersubband transitions to generate photons have become important sources of light in the mid-infrared region (5 /spl mu/m - 10 /spl mu/m). The primary application of coherent sources at these wavelengths is spectroscopy. For such applications it is important to quantify the photon noise in QCLs. In this paper a comprehensive model for the photon number fluctuations in QCLs is reported for the first time.
