A Diamond Lens Made Lead Vacancies Ten Times Brighter
One solid-immersion lens also enabled two-photon interference from a single defect center.
Summary
One solid-immersion lens also enabled two-photon interference from a single defect center.
Solid-immersion lenses fabricated on rough, high-temperature-annealed diamond increased lead-vacancy emission by about a factor of ten. Resonant excitation approached the transform-limited linewidth, and one center produced two-photon interference, supporting—but not completing—a path toward network nodes above four kelvin.
Why it matters
One solid-immersion lens also enabled two-photon interference from a single defect center.
Limits and context
- Resonant excitation approached the transform-limited linewidth, and one center produced two-photon interference, supporting—but not completing—a path toward network nodes above four kelvin.
Key claims
