Abstract

We demonstrate a method to perform spectroscopy of near-infrared single photons without the need of dispersive elements. This method is based on a photon energy resolving transition edge sensor and is applied for the characterization of a widely wavelength tunable narrow-band single photons emitted from a crystalline whispering gallery mode resonator. We measured the emission wavelength of the generated signal and idler photons with a precision of up to 2 nm.
