ESE Seminar: “Quantum Dot Plasmon Nanolasers”
November 24, 2020 at 12:00 PM - 1:00 PM
Miniaturized light sources are critical for next-generation on-chip photonic devices. Plasmon-based
lasers and surface plasmon amplified spontaneous emission of radiation (spasers) have received
significant attention since their prediction over a decay over a decade ago. Major advances have
included subwavelength footprint sizes, room-temperature operation, far-field emission
directionality, and understanding of the lasing mechanism. Notably, one simple architectural design
for the plasmonic lasing cavity—nanoparticle lattices—has emerged as a powerful platform to
achieve exquisite control over the coherent light. This talk will describe a nanolaser design based on
colloidal CdSe-CdS core-shell quantum dots (QDs) conformally coated on two-dimensional arrays of
Ag nanoparticles. These QD-plasmon lasers can show directional emission by exploiting high
symmetry points in the lattices and tailorable polarization patterns depending on the QD film
thickness. We will discuss prospects for achieving any desired lasing emission angle from these
room-temperature hybrid nanolasers.

Professor of Chemistry and Materials Science and Engineering; Chair of the Department of Chemistry, Northwestern University
Teri W. Odom is the Charles E. and Emma H. Morrison Professor of Chemistry and Chair of the Chemistry Department at Northwestern University. She is an expert in designing structured nanoscale materials that exhibit extraordinary size and shape-dependent optical and physical properties. Odom has pioneered a suite of multi-scale nanofabrication tools that have resulted in plasmon-based nanoscale lasers that exhibit tunable color, flat optics that can manipulate light at the nanoscale, and hierarchical substrates that show controlled wetting and super-hydrophobicity. She has also invented a class of biological nanoconstructs that are facilitating unique insight into nanoparticle-cell interactions and that show superior imaging and therapeutic properties because of their gold nanostar shape. Odom is a Member of the American Academy of Arts and Sciences (AAAS) and a Fellow of the Materials Research Society (MRS), the Royal Society of Chemistry (RSC), the American Chemical Society (ACS), the American Physical Society (APS), and the Optical Society of America (OSA). Select honors and awards include: the RSC Centenary Prize; the ACS National Award in Surface Science; a Research Corporation TREE Award; a U.S. Department of Defense Vannevar Bush Faculty Fellowship; a Radcliffe Institute for Advanced Study Fellowship at Harvard University; an NIH Director’s Pioneer Award; the MRS Outstanding Young Investigator Award; the National Fresenius Award from Phi Lambda Upsilon and the ACS; an Alfred P. Sloan Research Fellowship; and a David and Lucile Packard Fellowship in Science and Engineering.
Odom was founding Chair of the Noble Metal Nanoparticles Gordon Research Conference (GRC) and founding Vice-Chair of the GRC on Lasers in Micro, Nano, Bio Systems. She was an inaugural Associate Editor for Chemical Science and founding Executive Editor of ACS Photonics. She is Editor-in-Chief of Nano Letters. Odom’s Personal Story of Discovery was featured by ACS Publications.
