Characterization of photon pairs generated by a silicon ring resonator under electrical self-pumping

TL;DR

This paper demonstrates the generation of nonclassical photon pairs in a silicon ring resonator using a self-pumping scheme within a lasing cavity, enabling resonance filtering without active stabilization.

Contribution

It introduces a novel self-pumping method for photon pair generation in silicon resonators, simplifying the process by eliminating the need for active resonance stabilization.

Findings

Photon pairs are successfully generated and correlated within the resonator.

The self-pumping scheme maintains lasing within a specific resonance without active tuning.

Stimulated emission measurements confirm the nonclassical nature of the photon pairs.

Abstract

We report on the generation of nonclassical states of light in a silicon ring resonator in a selfpumping scheme. The ring is inserted in a lasing cavity, for which it acts as a filter, so that the lasing always occurs within a selected ring resonance, without active stabilization of the resonance frequency. We show the emission of coincident photon pairs and study their correlation properties through the reconstruction of the measurements via stimulated emission.
