Optical-transition parameters of the silicon <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline" overflow="scroll"><mml:mi>T</mml:mi></mml:math> center
The silicon T center's narrow, telecommunications-band optical emission, long spin coherence, and direct photonic integration have spurred interest in this emitter as a spin-photon interface for distributed quantum computing and networking. However, key parameters of the T center's spin-selective optical transitions remain undetermined or ambiguous in the literature. In this paper, we present a Hamiltonian of the T center TX state and determine key parameters of the optical transition from ${\mathrm{T}}_{0}$ to ${\mathrm{TX}}_{0}$ from a combined analysis of published results, density functional theory, and new spectroscopy. We resolve ambiguous values of the internal defect potential in the literature, and we present the first measurements of electrically tuned T center emission. As a result, we provide a model of the T center's optical and spin properties under strain, electric, and magnetic fields that can be utilized for realizing quantum technologies.
