Spectrally multimode SU(1,1) interferometer operating in the sub-nanosecond regime and the 1.57/3.3µm range

A non-linear interferometer is implemented using 1.57/3.3µm Spontaneous Parametric Down-conversion (SPDC) pumped by a 1.064µm sub-ns pulsed laser source. The interference pattern due to induced coherence is observed in the high gain regime and on the intensity of the signal spectrum.

Abstract

A non-linear interferometer is implemented using 1.57/3.3µm Spontaneous Parametric Down-conversion (SPDC) pumped by a 1.064µm sub-ns pulsed laser source. The interference pattern due to induced coherence is observed in the high gain regime and on the intensity of the signal spectrum.
