Coupled Quantum Dots and Photonic Crystals for Nanophotonic Devices

摘要

To this end we worked to combine engineered QD5 with engineered PC cavities to explore and exploit simultaneous electronic and optical confinement. Technical thrusts included Nanocavity design and device development along with integration with the quantum dot (QD) active region. The first approach which we considered was to incorporate self-assembled QD5 into the starting epitaxial material, where the PC nanocavities are fabricated after growth. The PCs design and fabrication was optimized for high cavity Q and minimal cavity volume. In parallel, we developed nanopatterning capability to arbitrarily place a single QD or an ensemble of identical QUs within the PC.
