Carrier Dynamics and Modulation Properties of Selective Area Epitaxial Quantum Structures in Dielectric Nanophotonic Cavities for High Speed and Energy Efficient Lasers
Abstract
The overall project goal is to investigate theoretically and experimentally carrier dynamics and modulation properties of low dimensional quantum structures in heterostructure photonic crystal cavities for high modulation bandwidth and high energy efficient emitters. Selective area epitaxial Quantum dots (SAE-QDs) with high density and high homogeneity will be investigated to potentially unlock the full potentials of these artificial atoms with high quantum efficiency, high differential gain, and temperature insensitive physical properties. The coupling of these SAE-QDs with both traditional and nanoscale dielectric optical cavities will also be investigated with modified spontaneous emission and controlled light-matter interactions for lasers with low lasing threshold, high modulation bandwidth and low damping, high operation temperatures. The ultimate scaling towards attojoule (aJ) energy efficiency and a thermal operation will also be analyzed, with strategies in active material volume scaling, strain engineering and optical cavity scaling.
