Note: Phase sensitive detection of photoluminescence with Fourier transform spectroscopy.

ABSTRACT

Although known for more than twenty years, there is limited information in the literature regarding the experimental parameters of lock-in based phase sensitive emission detection in conjunction with Fourier spectrometers. For this technique - also known as double modulation spectroscopy - we present a guideline for parameter optimization by measuring the photoluminescence of InSbTe at cryogenic temperatures.
