Stark tuning of telecom single-photon emitters based on a single Er${}^{3+}$

Abstract

The implementation of scalable quantum networks requires photons at the telecom band and long-lived spin coherence. The single Er${}^{3+}$ in solid-state hosts is an important candidate that fulfills these critical requirements simultaneously. However, to entangle distant Er${}^{3+}$ ions through photonic connections, the emission frequency of individual Er${}^{3+}$ in solid-state matrix must be the same, which is challenging because the emission frequency of Er${}^{3+}$ depends on its local environment. Herein, we propose and experimentally demonstrate the Stark tuning of the emission frequency of a single Er${}^{3+}$ in a Y${}_2$SiO${}_5$ crystal by employing electrodes interfaced with a silicon photonic crystal cavity. We obtain a Stark shift of 182.9 $\pm$ 0.8 MHz which is approximately 27 times of the optical emission linewidth, demonstrating the promising applications in tuning the emission frequency of independent Er${}^{3+}$ into the same spectral channels. Our results provide a useful solution for construction of scalable quantum networks based on single Er${}^{3+}$ and a universal tool for tuning emission of individual rare-earth ions.
