Characterizing ultrashort optical pulses using second-order nonlinear nanoprobes
(AIP Publishing, 2010-12-01)
We report a second-order nonlinear nanoprobe for characterizing ultrafast optical near fields. The proposed nanoprobe comprises second harmonic nanocrystals attached to a carbon nanotube, which is in turn attached to a ...
Development of a nonlinear nanoprobe for interferometric autocorrelation based characterization of ultrashort optical pulses
(AIP Publishing, 2010-01-01)
Near-field scanning can achieve nanoscale resolution while ultrashort pulse diagnostic tools can characterize femtosecond pulses. Yet currently it is still challenging to nonperturbatively characterize the near field of ...
Irreversible adsorption of gold nanospheres on fiber optical tapers and microspheres
(AIP Publishing, 2012-04-01)
We study the adsorption of gold nanospheres onto cylindrical and spherical glass surfaces from quiescent particle suspensions. The surfaces consist of tapers and microspheres fabricated from optical fibers and were coated ...
