Electrically-driven silicon single-photon source with polarization control
Abstract
Quantum light sources are essential for advancements in quantum information processing, communication, sensing, and imaging. However, there s a critical need for single-photon sources (SPS) that combine key attributes- electrical pumping, monochromaticity, low jitter, emission at a telecom wavelength, miniaturization, and being compatible and ready for integration with silicon electronics.This project proposes exploring novel pathways to achieving electrical single-photon generation with polarization control. Our goal is to develop a groundbreaking SPS that fulfills all these requirements in a single device - unlike any existing source. Building upon our previous limit-breaking success in generating stimulated emission from silicon G-centers in the telecom O-band, this project pushes the boundary to the opposite limit towards electrically-pumped single-photon emission. It has the potential to pave the way for a first all-silicon, electrically driven, and monochromatic SPS. Being fully compatible and readily integrable with silicon circuitry for quantum processing, this silicon SPS is also expected to operate at a higher temperature than the current record for optically pumped counterpart, and incorporate a mechanism for polarization control. The latter is both differentiating and critically needed and will be attempted by 3D chiral plasmonic near-field coupling. The unprecedented nature of this endeavor naturally brings its own unique challenges, which this AOARD-Korea collaborative project will tackle. The complementary expertise, capabilities, and facilities brought forward by the combined team from two countries form a solid foundation for the pursuit. Following a comprehensive plan, the team will endeavor a 3-year effort to address the research questions and limiting factors identified in pilot studies and in the proposal, while exploring new research avenues that can be expected to emerge in the course of such explorations.
