Tapered Waveguide Coupler and Spectrometer
U.S. Patent No. 8,977,086 issued March 10th 2015

Dr. Raymond DeCorby of the University of Alberta’s Department of Electrical and Computer Engineering received an issued U.S. patent describing a method of forming a tapered hollow waveguide by stacking multiple light guiding layers.

These tapered hollow waveguides have potential use as an optical coupler or spectrometer for lab-on-chip applications, optofluidic microsystems or any nanoscale optical network with applications in medical diagnostics, nanoscale sensing, and computing among others.
