Phase sensitive detection of dipole radiation in a fiber-based high numerical aperture optical system
A. N. Vamivakas, M. Dogan, S. B. Ippolito +4
We theoretically study the problem of detecting dipole radiation in an optical system of high numerical aperture in which the detector is sensitive to \textit{field amplitude}. In…
Chirality dependence of the radial breathing phonon mode density in single wall carbon nanotubes
A. N. Vamivakas, Y. Yin, A. G. Walsh +3
A mass and spring model is used to calculate the phonon mode dispersion for single wall carbon nanotubes (SWNTs) of arbitrary chirality. The calculated dispersions are used to dete…
Optical Determination of Electron-Phonon Coupling in Carbon Nanotubes
Y. Yin, A. Vamivakas, A. Walsh +4
We report on an optical method to directly measure electron-phonon coupling in carbon nanotubes by correlating the first and second harmonic of the resonant Raman excitation profil…
Tunable Resonant Raman Scattering from Singly Resonant Single Wall Carbon Nanotubes
Y. Yin, A. G. Walsh, A. N. Vamivakas +7
We perform tunable resonant Raman scattering on 17 semiconducting and 7 metallic singly resonant single wall carbon nanotubes. The measured scattering cross-section as a function l…
Exciton mediated one phonon resonant Raman scattering from one-dimensional systems
A. N. Vamivakas, A. Walsh, Y. Yin +3
We use the Kramers-Heisenberg approach to derive a general expression for the resonant Raman scattering cross section from a one-dimensional (1D) system explicitly accounting for e…
