Nanophotonics at Stanford University
Welcome! We are the research group of Jen Dionne, Associate Professor of Materials Science and Engineering at Stanford University. We are a diverse team of materials scientists, chemists, applied physicists, electrical engineers, chemical engineers, bioengineers and mechanical engineers, researching new ways to control light-matter interactions.

We imagine a world where diseases like cancer, Alzheimer's and tuberculosis are detected and cured with light; where solar cells provide abundant clean energy; and where cell phones compute at the speed of light. We then strive to make that future a reality through development of new nanophotonic materials, methods, and devices.

Featured Research

I. High quality factor dielectric metasurfaces for ultraviolet circular dichroism spectroscopy:

Jack and Mark designed high quality factor metasurfaces to enhance chiral light matter interactions in the ultraviolet. Their research, published in ACS Photonics, utilizes asymmetric metasurfaces that strongly concentrate twisted light and enhance the chiral absorption of small molecules. This work paves the way for ultrasensitive chiral-optical spectroscopies and efficient light mediated enantiomer separation.

II. Rapid identification of pathogenic bacteria using Raman spectroscopy and deep learning:

Shing-Shing and Amr, in collaboration with team-members from computer science and pathology, use Raman spectroscopy combined with machine learning to enable accurate classification of pathogenic bacteria. Their research, published in Nature Communications, amassed the largest bacterial cell Raman dataset to date, spanning the 30 species most commonly seen as the cause of bloodstream infection and representing the majority of infections in intensive care units worldwide. Their research lays a foundation for fast and tailored bacterial identification and antibiotic treatment.

III. Sub-20 nm Core–Shell–Shell Nanoparticles for Bright Upconversion and Enhanced Förster Resonant Energy Transfer:
