“…In contrast, the heterodyne technique of spectral interferometry [14] employs a delayed reference pulse together with spectrally resolved detection for full characterization (amplitude and phase) of electric fields, e.g., transmitted through a periodic nanoslit/-hole array using weakly focused fields [15]. In a related heterodyne technique the interference is detected without spectral resolution and the delay time between signal and reference pulse has to be scanned.…”

Abstract:Plasmonic modes supported by noble-metal nanostructures offer strong subwavelength electric-field confinement and promise the realization of nanometer-scale integrated optical circuits with well-defined functionality. In order to measure the spectral and spatial response functions of such plasmonic elements, we combine a confocal microscope setup with spectral interferometry detection. The setup, data acquisition, and data evaluation are discussed in detail by means of exemplary experiments involving propagating plasmons transmitted through silver nanowires. By considering and experimentally calibrating any setup-inherent signal delay with an accuracy of 1 fs, we are able to extract correct timing information of propagating plasmons. The method can be applied, e.g., to determine the dispersion and group velocity of propagating plasmons in nanostructures, and can be extended towards the investigation of nonlinear phenomena.

The transmission dynamics of EOT have been studied theoretically 13,[18][19][20][21] and experimentally.…”

We have studied the frequency-dependent transmission time delay of femtosecond (fs) laser pulses through subwavelength hole arrays in aluminum films using the up-conversion technique. The pulse delays measured at different wavelengths mainly follow the far-field transmission profile of the surface plasmon polariton (SPP) resonances. Temporal delays of 60fs and 100fs were found at the major SPP resonance in the single-layer and double-layer samples. A coupled-SPP transmission model is used to explain the temporal dynamics of the transmission process. Our experiment shows that the weak coupling between the SPP waves on different metal/dielectric interfaces leads to the large temporal delay of the transmitted pulses.

“…Some of the most important reasons for choosing such a structure are that (i) nanoslit arrays with slit widths in the 20-100 nm range can now be fabricated with high precision using electron beam lithography or focussed ion beam milling, (ii) the optical properties of nanoslit arrays deposited on passive dielectric substrates have recently been studied in some detail [30][31][32][33] and (iii) quantum wells, when optically pumped, provide high gain coefficients which may be sufficient to significantly reduce SPP damping due to Ohmic losses in the metal and potentially even reach surface plasmon polariton lasing. From the above-cited studies and others it is now understood that such metal nanoslit arrays with grating periodicities in the range of one micron show quite large transmission coefficients at certain resonance wavelengths, connected to SPP excitation at either the metal/air or metal/dielectric interface.…”

“…The calculations are based on a diffraction model employing approximate surface impedance boundary conditions at the interfaces [33,34]. This model has been used quite successfully to interpret earlier experimental results [30][31][32]. The resonances in the reflection spectra arise from grating coupling to SPP modes at either the air/metal (AM) or semiconductor/metal interface.…”

We have recently studied excitonic effects on the optical properties of single‐walled carbon nanotubes by means of two‐photon spectroscopy and time‐resolved photoluminescence spectroscopy. For nanotubes with diameters between 6.8 Å and 9.0 Å, the two‐photon spectra give evidence for large binding energies between 300 meV to 400 meV. Theoretical simulations of these spectra indicate that the lowest energy exciton state in nanotubes is an optically dark exciton, which has profound implications on the luminescence yield and exciton dynamics in single‐walled nanotubes. Indeed, time‐resolved photoluminescence measurements of individual nanotubes reveal low quantum yields and rather short exciton lifetimes ranging from 10 ps to 200 ps, which are affected by exciton relaxation between bright and dark states and non‐radiative exciton recombination. These results suggest that a control of the radiative lifetime of nanotube excitons may be a viable strategy for enhancing their luminescence yield. Here, we propose that exciton‐coupling to surface plasmon polaritons in metallic nanostructures may result in a substantial enhancement of the radiative exciton decay rate. Two‐photon luminescence excitation spectra of single‐walled carbon nanotubes. The luminescence intensity is plotted as a function of excitation and detection wavelength. The various two‐photon resonances are assigned to nanotube species with different chiral indices (n,m), as indicated in the figure. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
