GHz-Clocked Indistinguishable Single-Photon Generation at Telecom C-Band Wavelengths

Semiconductor QD achieves 2.5 GHz single-photon generation at telecom C-band with g²(0)<4% multiphoton suppression and >85% two-photon interference visibility, matching theoretical limits via Purcell-enhanced biexciton cascade excitation.

Resonance Fluorescence Spectrum of a Three-Level Quantum Dot-Cavity System Under Incoherent Pumping

Numerical study of a Vee-type three-level quantum dot in a microcavity shows how quantum interference parameter β and incoherent pumping reshape the Mollow triplet spectrum, enabling tunable single-photon emission for quantum communication.

Strain-Engineered Site-Controlled Quantum Dots for Telecom O-Band via Buried Stressors

Buried AlAs/Al₂O₃ stressors enable deterministic InGaAs/GaAs QDs emitting at ~1.3 µm without strain-reducing layers, achieving 95% single-photon purity at 4K and 72% at 77K—a scalable, industry-compatible route to fiber-ready quantum photonic sources.
