  2. 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...

  3. 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...

  4. 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,...
