"Positioning of Quantum Dots for Photonic Switching"

by Chad Ropp

Friday, March 27, 2009 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Assistant Professor Edo Waks

Quantum dots are proving to be excellent candidates for the active elements of solid state based photonic switches. One serious drawback to quantum dots is their natural inhomogeneity resulting from fabrication processes. Any future for quantum dot technology depends on our ability to circumvent this problem. This presentation will explain a setup for actively selecting and positioning colloidal quantum dots using microfluidic control techniques in conjunction with crosslinking fluid chemistry. Results of quantum dot manipulation as well as fluid solidification will be shown.
