In our new PRX Quantum paper, PhD student Camille Bowness & postdoc Simon Meynell study spectral wandering of single colour centres in silicon nanocavities. We show wandering is mainly laser-induced, and narrow the effective excitation linewidth using a resonance-check scheme. go.aps.org/3IjO63h

Excited to share our new paper by PhD student Michael Dobinson in Nature Photonics: rdcu.be/eFFQf

We show single-photon emission + spin initialization by electrical injection in cavity-enhanced, single-defect silicon diodes. Much more to come on these devices!

Electrically triggered spin–photon devices in silicon
Nature Photonics - Two types of on-chip silicon device utilizing silicon T centres are developed: an O-band light-emitting diode and an electrically triggered single-photon source. Further, a new...

Very excited to share a new preprint by my PhD student Camille Bowness and postdoc Simon Meynell: arxiv.org/abs/2504.09908

The spectral fluctuations of integrated T centres are primarily laser-driven, and resonance checks can significantly increase entanglement rates in T centre quantum networks.
Laser-induced spectral diffusion and excited-state mixing of silicon T centres
To find practical application as photon sources for entangled optical resource states or as spin-photon interfaces in entangled networks, semiconductor emitters must produce indistinguishable photons ...
