Optical Synthesis of Terahertz and Millimeter-Wave Frequencies with Discrete Mode Diode Lasers
Stephen O'Brien, Simon Osborne, David Bitauld +5
It is shown that optical synthesis of terahertz and millimeter-wave frequencies can be achieved using two-mode and mode-locked discrete mode diode lasers. These edge-emitting devic…
Passive harmonic mode-locking by mode selection in Fabry-Perot diode lasers with patterned effective index
D. Bitauld, S. Osborne, S. O'Brien
We demonstrate passive harmonic mode-locking of a quantum well laser diode designed to support a discrete comb of Fabry-Perot modes. Spectral filtering of the mode spectrum was ach…
Growth and structural characterization of pyramidal site-controlled quantum dots with high uniformity and spectral purity
Valeria Dimastrodonato, Lorenzo O. Mereni, Robert J. Young +1
This work presents some fundamental features of pyramidal site-controlled InGaAs Quantum Dots (QDs) grown by MetalOrganic Vapour Phase Epitaxy on patterned GaAs (111)B substrate. T…
Deformation Potentials and Electron-Phonon Coupling in Silicon Nanowires
F. Murphy-Armando, G. Fagas, J. C. Greer
The role of reduced dimensionality and of the surface on electron-phonon (e-ph) coupling in silicon nanowires is determined from first principles. Surface termination and chemistry…
Nanoscale single- and multi-photon mapping of optical fields
David Bitauld, Francesco Marsili, Alessandro Gaggero +5
The study of optical phenomena on the subwavelength scale is becoming increasingly important in photonics, particularly in the fields of nanoemitters, photonic crystals and plasmon…
