ECE 616 Student Presentation: Dual-Comb Spectroscopy
02 Mar 2012 | | Contributor(s):: Andrew J Metcalf
Dual comb spectroscopy is introduced, a technique that is basedon the beating of two frequency combs. A sample is first interrogated bythe combs before they are beat together via photodiode which down convertsthe signal from the optical to RF domain where it can be processed with electronics. A...
ECE 616 Student Presentation: MIIPS - Pulse-Shaper Enabled Pulse Measurement and Shaping
05 Apr 2012 | | Contributor(s):: Liang Guo
Common ultrafast laser pulse characterization methods, such as autocorrelation, frequency-resolved optical gating (FROG), and spectral phase interferometry for direct electric-field reconstruction (SPIDER), can only measure the pulse characteristics, whose use is limited when measuring and...
ECE 616 Student Presentation: Ultrafast Non-linear Plasmonics
02 Mar 2012 | | Contributor(s):: Gururaj V Naik
Plasmonics has gained significant attention in the recent days owing to its capability of providing sub-wavelength confinement of light. As a consequence of sub-wavelength confinement of electric field, the field intensity issignificantly enhanced. High field intensity achieved by plasmonics,...

Experiment vs. Modelling: What's the problem?
10 Aug 2009 | | Contributor(s):: William L. Barnes
Progress in plasmonics has been greatly assisted by developments in experimental techniques and in numerical modelling. This talk will look at some of the difficulties that emerge when comparisons are made between experiment and theory. Through the use of four examples I will illustrate what...
