Cavity behavior of second and third harmonic inhomogeneous solutions of Maxwell’s equations
(2010)
Article
Restricted access - publisher's policyWe study second and third harmonic generation of ultrashort pulses in a cavity environment and focus on the role of a phase locking phenomenon that causes the pump to trap and drag the generated harmonic fields. The results ... -
Enhanced efficiency of the second harmonic inhomogeneous component in an opaque cavity
(2011-05-15)
Article
Open AccessIn this Letter, we experimentally demonstrate the enhancement of the inhomogeneous second harmonic conversion in the opaque region of a GaAs cavity with efficiencies of the order of 0.1% at 612nm, using 3 ps pump pulses ... -
Harmonic generation in metallic, GaAs-filled nanocavities in the enhanced transmission regime at visible and UV wavelengths
(2011-01-19)
Article
Open AccessWe have conducted a theoretical study of harmonic generation from a silver grating having slits filled with GaAs. By working in the enhanced transmission regime, and by exploiting phase-locking between the pump and its ... -
New propagation effects in semiconductors in the UV range: inhibition of absorption, negative refraction, anomalous momentum states, sub-wavelength imaging and non-plamonic nanometer-size guided waves
(2009)
Conference report
Open AccessWe discuss new propagation effects in semiconductors at frequencies above the absorption including inhibition of linear absorption using phase-locked harmonic pulses, negative refraction, anomalous momentum states, ... -
Phase locked second harmonic etalon localization
(2009)
Conference report
Restricted access - publisher's policyDuring the last decades a phase locking phenomenon has been observed for second harmonic (SH) generation but only recently it was recognized as such in systematic studies. The general solution of the SHG from a linear/nonlinear ... -
Second-harmonic generation in disordered quadratic media: role of a ferroelectric domain structure
(2010)
Conference report
Open AccessWe study theoretically the second harmonic generation in a nonlinear quadratic crystal with random distribution of ferroelectric domains. We show that the specific features of disordered domain structure greatly affect the ... -
Second-harmonic generation in disordered quadratic media: role of a ferroelectric domain structure
(2010)
Conference report
Restricted access - publisher's policyNaturally grown ferroelectric crystals such as Strontium Barium Niobate (SBN) often exhibit an irregular multidomain structure with rod-like domains [1]. These disordered nonlinear quadratic crystals have attracted a ... -
The role of the phase locking phenomenon in the second and third harmonics cavity localization
(2009)
Conference report
Restricted access - publisher's policyWe theoretically and experimentally study how the phase-locking mechanism changes effective dispersion of the medium at the harmonic frequencies making them become localized inside a opaque cavity designed to be resonant ... -
Third harmonic generation at 223 nm in the metallic regime of GaP
(2011-03-14)
Article
Open AccessWe demonstrate second and third harmonic generation from a GaP substrate 500 μm thick. The second harmonic field is tuned at the absorption resonance at 335 nm, and the third harmonic signal is tuned at 223 nm, in a range ...
