High-$\beta$ lasing in photonic-defect semiconductor-dielectric hybrid microresonators with embedded InGaAs quantum dots

Kartik Gaur, Ching-Wen Shih, Imad Limame +6

We report an easy-to-fabricate microcavity design to produce optically pumped high-$\beta$ quantum dot microlasers. Our cavity concept is based on a buried photonic-defect for tight la…
