Nanomechanical forming studies of thin polymer films
(Trinity College (Dublin, Ireland). School of Physics, 2008)
Nanoimprint is a technique that involves mechanical patterning using a rigid
patterned stamp on a deformable thin film to produce nanostructures. It is
also a technique that is the focus of much research because of the ...
Magnetic Modes in Rare Earth Perovskites: A Magnetic-Field-Dependent Inelastic Light Scattering study
(2016)
Here, we report the presence of defect-related states with magnetic degrees of freedom in crystals of LaAlO3 and several other rare-earth based perovskite oxides using inelastic light scattering (Raman spectroscopy) at low ...
Collisional Broadening of Semiconductor Microcavity Polaritons
(2002)
We measure the effect of intensity on the homogeneous linewidth of two high finesse semiconductor microcavities in the strong coupling regime using degenerate four‐wave mixing. We find that the collisional broadening due ...
Spectral overlap dependence of enhanced energy transfer near small au nanoparticles
(2014)
We consider the effect of gold nanospheres of subwavelength dimension on the energy transfer rates and efficiencies between donor-acceptor pairs placed near the nanospheres. We investigate theoretically the ...
Characterization, Simulation and Optimization of Surface Etched Slotted Tunable Laser Diodes
(Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
The past decades have seen near exponential growth in internet traffic. To meet this growth, optical communication networks continue to branch deeper into network architectures, replacing electrical based communication. ...
Observation of intermultiplet transitions in Sm(Fe11Ti) by inelastic neutron scattering
(American Physical Society, 1990)
Magnetic neutron spectroscopy of SMFe11Ti reveals a dispersionless electronic excitation corresponding to transitions between levels of the exchange-split ground- and first-excited-state multiplets of the Sm3+ ion. The ...
Tensor-network method to simulate strongly interacting quantum thermal machines
(2020)
We present a methodology to simulate the quantum thermodynamics of thermal machines which are built from an interacting working medium in contact with fermionic reservoirs at a fixed temperature and chemical potential. Our ...
Investigation of polarization dependent gain in a bulk SOA
(2007)
The polarization dependence of the gain dynamics in a bulk semiconductor optical amplifier is examined using two experimental setups. The first experimental investigation is based on four-wave mixing. Using a low-pass ...
