Towards a Heralded Single Photon Source Model Based on Photonic Crystal: Constraints and Feasibility
In this paper we present a scheme of a heralded single photon source based on active two-dimensional photonic crystal (PC) over LiNbO3 excited by continuous pump laser source. The use of 2D photonic crystal could improve the conversion light efficiency and obtain height density of mode (DOM) at 1310nm and 1550nm, which will increase the probability of obtaining single photon. The scheme is based on two photonic crystals arranged in serial configuration. The first one acts as extractor of the two wavelengths, and the second as a demultiplexer and can be considered as a time-delay coupler. Also constraints related to manufacturing process are reported in order to show performances of the CP on the heralded single photon source model.
