Abstract
This work presents a correlator for constructing the second-order autocorrelation function g(2)(τ), implemented on a field-programmable gate array (FPGA). The device is designed for high-precision registration of time intervals between photons detected from single emitters. The use of an FPGA enabled a time resolution of 185 ps and real-time event processing. Experimental data demonstrating photon antibunching with g(2)(0) < 0.5, a characteristic feature of single quantum emitters, are presented. The device can be used for photon correlation analysis in quantum optics and in studies involving single quantum emitters.
