Abstract
T centers in silicon could serve as efficient quantum memories based on spin-photon interface. But these emitters have long excited state lifetimes and are therefore dim. We demonstrate high-efficiency single photon emission from the zero-phonon line of a single T center using a nanobeam. The tapered nanobeam features coupling efficiency of 71% into a lensed fiber, enabling an order of magnitude improvement in photon count rates as compared to previously reported values. Consequently, we demonstrate single photon emission from the zero-phonon line, representing the coherent emission from the T center. Our result is an important step towards CMOS-integrated spin-photon interfaces.
