Highly Efficient Single-Photon Sources Based on Nanoscale Optical Positioning and Hybrid Photonic Integration Single photon sources are essential to quantum key distribution quantum computation and quantum optical communication. This SuperUROP aims to develop highly efficient fiber-integrated single photon sources for various quantum information processing applications. Self-assembled epitaxially-grown semiconductor quantum dots (QDs) are among the best candidates for on-demand single photon sources but incorporating them into engineered photonic environments presents significant challenges. In order to efficiently extract broadband single photons emitted by the QDs we will use "bullseye" gratings fabricated in GaAs with a single layer of embedded InAs QDs. My goal is to functionalize optical fibers with such QD-embedded bullseyes to create versatile "plug and play" single photon sources.
As a senior in electrical engineering and physics I have always been fascinated by the study of matter and light at the most fundamental level. Building on my prior experience in electronic device fabrication and micro-manipulation I am excited to have the opportunity to apply the knowledge I gained in my electromagnetics and quantum physics classes to a cutting-edge research problem in quantum engineering.
