Abstract

Single-photon emitters (SPEs) are critical to the realization of various applications, including quantum information technology, quantum sensing, and quantum communication. As stable and bright SPEs, point defects in wide bandgap semiconductors are compatible with existing well-matured semiconductor technologies, making integration with semiconductor devices very simple. Here we report SPEs in cubic silicon carbide (3C-SiC) emitting in the visible range. The emitters can be excited stably by a green laser at ambient temperature and have stable photoluminescence (PL) intensity reaching up to 245 × 103 counts per second (cps). In experiments, the degree of linear polarization of both excitation and emission can reach 80%. Together with the fact that silicon carbide (SiC) is a material that is easy to grow and fabricate, these properties show the advantage and prospect of SPEs in SiC for applications in quantum networks.

Abstract

In order to solve the technical bottleneck of the sensitive detection of the optically detected magnetic resonance (ODMR) signal from the nitrogen vacancy (NV) color centers in the diamond by taking the advantage of the directional amplification of stimulated radiation' an optical amplification system was set up to investigate the stimulated radiation of NV color centers in diamond' where the maximum amplification efficiency reached 10. 5%. Besides' it is found that the amplification efficiency is related to the pump laser power and signal laser power as well as the polarization states of the two lasers. The results show that it is promising to use the amplification of stimulated radiation to replace the fluorescence in the ODMR measurement with NV color centers in the application of remote sensing.
