Discovery Park Undergraduate Research Internship Program

"Ultrafast single-photon emitter for secure quantum communication"

About the Project

Project Time & Type:
Summer 2017 - DURI
Research area(s):
Nanophotonics, Quantum Optics
Project Description:
Information privacy and communication security are among the greatest issues of our time. Quantum cryptography techniques may lead to communication systems that exclude the possibility for eavesdropping based on the most fundamental laws of physics. Efficient single photon sources are vitally important for such systems. An efficient and fast single-photon source could be realized by coupling a solid-state atomic defect to a nanophotonic structure. The proposed project aims at creating and characterizing a single photon source based on a nanodiamond coupled to a plasmonic cavity that is much smaller than the wavelength of light. A fast and simple AFM-based technique must be developed to assemble the structure. The procedure should allow to transport metallic nanocubes and nanodiamonds across different substrates and assemble these particles with nanometer precision.
Expected Student Contributions:
1. Assembly of a nanophotonic structures using an atomic force microscope (AFM); 2. Optical characterization of the assembled structures (single-photon emitters).
