A tuneable wavelength reference for chip-scale laser cooling
S. Dyer, K. Gallacher, U. Hawley +6
We demonstrate a tuneable, chip-scale wavelength reference to greatly reduce the complexity and volume of cold-atom sensors. A 1 mm optical path length micro-fabricated cell provid…
Strain analysis of Ge micro disk using precession electron diffraction
Aneeqa Bashir, Ross. W. Millar, Kevin Gallacher +7
The recently developed precession electron diffraction (PED) technique in scanning transmission electron microscopy (STEM) has been used to elucidate the local strain distribution…
Mid Infrared Nonlinear Plasmonics using Germanium Nanoantennas on Silicon Substrates
Marco P. Fischer, Aaron Riede, Kevin Gallacher +8
We demonstrate third harmonic generation in plasmonic antennas made of highly doped germanium and designed to be resonant in the mid infrared. Owing to the near-field enhancement,…
Disentangling nonradiative recombination processes in Ge micro-crystals on Si substrates
F. Pezzoli, A. Giorgioni, K. Gallacher +9
We address nonradiative recombination pathways by leveraging surface passivation and dislocation management in micron-scale arrays of Ge crystals grown on deeply patterned Si subst…
Mid-Infrared Plasmonic Platform based on Heavily Doped Epitaxial Ge-on-Si: Retrieving the Optical Constants of Thin Ge Epilayers
Leonetta Baldassarre, Eugenio Calandrini, Antonio Samarelli +8
The n-type Ge-on-Si epitaxial material platform enables a novel paradigm for plasmonics in the mid-infrared, prompting the future development of lab-on-a-chip and subwavelength vib…
