Interband Cascade Laser Photon Noise

Abstract

We report measurements of the low-frequency photon noise and the relative intensity noise of an interband cascade laser as a function of laser current at 30 K and 100 K. Away from threshold, the laser primarily exhibits a frequency-independent photon noise spectral density in agreement with theory. At threshold, the observed photon noise spectral density exhibits large fluctuations at closely-spaced discrete frequencies. Thermal effects at 100 K result in a large increase in the photon noise above threshold.
