Bright Single-Photon Sources Based on Anti-Reflection Coated Deterministic Quantum Dot Microlenses

We report on enhancing the photon-extraction efficiency (PEE) of deterministic quantum dot (QD) microlenses via anti-reflection (AR) coating. The AR-coating deposited on top of the curved microlens surface is composed of a thin layer of Ta2O5, and is found to effectively reduce back-reflection of li...
