Special AEP Seminar, Friday May 9 at 2 pm
Jiuen Lee, Ph.D. from the University of Michigan will be giving a seminar titled “Temporal and Spatial Control of Quantum Dots for On-Chip Integration” on Friday May 9 at 2 pm in Physical Sciences 120.
Abstract
Quantum dots (QDs) are nanostructures that confine electrons in three spatial dimensions. Due to their discrete atom-like energy levels, a wide variety of applications related to the optical properties of dots are possible. One such application is to integrate a QD in a photonic crystal cavity to enable the enhanced interaction between electrons and photons. Such hybrid systems of QD electrons and cavity photons can be an interesting platform for both the fundamental study of light-matter interactions and applications in information processing. In the first part of this talk, we focus on the temporal dynamics of single QDs coupled to a photonic cavity. In particular, an optical experiment using two time-delayed ultrafast pulses enables the quantitative description of the emission enhancement and reveals the nonlinearity of various transitions in single QDs. In the second part, we discuss a tool that can deterministically couple a dot to a cavity. Since the dot-cavity coupling efficiency depends on their spatial overlap, the ability to control QD positions at the fabrication level is highly desirable. We use a focused-ion-beam to pattern QDs at predetermined locations and evaluate their fidelity and optical properties for practical applications. All these experiments will be discussed in the context of developing scalable quantum information processing on a chip.
