Sažetak
In our recent work we have investigated generation of additional degrees of freedom (DOF) in laser locked high Q Fabry–Perot (FP) cavity using both single and double pass experimental setup. In our dichroic cavity setup we showed that beside widely used polarization DOF’s, it is possible to change frequency of the beam using AOM, and observe them resonate in the cavity as different TEM modes. This way we obtained additional DOF in a manner of transverse electric field distribution. Our goal is investigation of single photon behaviour in dichroic FP resonator. In the first experimental setup we are observing coincidences between a trigger pulse driving EOM and the pulse generated by FP cavity reflected and transmitted photons being detected on SPAD’s. For that purpose we employed pseudo-single photon source where faint laser pulse (FLP) is additionally switched by fast EOM, where approximately 5% of FLP’s contains more than one photon. Custom made SPAD’s were used in combination with FPGA as photon counters. In the following setup we will implement two distinguishable photonic states and test mutual coincidence while cavity is locked for one of these states. Possible applications are in fundamental research - nature of the quantum vacuum ; and in quantum technology: interaction free detectors, quantum gates or in all-optical photonic processing
