Self-organized metal nanostructures through laser driven thermocapillary convection
C. Favazza, J. Trice, R. Kalyanaraman +1
When ultrathin metal films are subjected to multiple cycles of rapid melting and resolidification by a ns pulsed laser, spatially correlated interfacial nanostructures can result f…
The convolution theorem for nonlinear optics
Hernando Garcia, Ramki Kalyanaraman
We have expressed the nonlinear optical absorption of a semiconductor in terms of its linear spectrum. We determined that the two-photon absorption coefficient in a strong DC-elect…
Self consistent determination of plasmonic resonances in ternary nanocomposites
Hernando Garcia, Justin Trice, Ramki Kalyanaraman +1
We have developed a self consistent technique to predict the behavior of plasmon resonances in multi-component systems as a function of wavelength. This approach, based on the tigh…
Nanostructure and microstructure of laser-interference induced dynamic patterning of Co on Si
L. Longstreth-Spoor, J. Trice, H. Garcia +2
We have investigated the nanostructure and microstructure resulting from ns laser irradiation simultaneous with deposition of Co films on Si(001) substrates. The spatial order and…
Robust nanopatterning by laser-induced dewetting of metal nanofilms
Christopher Favazza, Ramki Kalyanaraman, Radhakrishna Sureshkumar
We have observed nanopattern formation with robust and controllable spatial ordering by laser-induced dewetting in nanoscopic metal films. Pattern evolution in Co film of thickness…
A compound figure of merit for photonic applications of metal nanocomposites
Hernando Garcia, Hare Krishna, Ramki Kalyanaraman
Selecting nanocomposites for photonic switching applications requires optimizing their thermal, nonlinear and two-photon absorption characteristics. We simplify this step by defini…
