Near-infrared luminescent polymer amplifiers and microlasers
(Trinity College (Dublin, Ireland). School of Physics, 2008)
Near-infrared optical gain in luminescent polymeric slab asymmetric waveguides has been investigated by use of amplified spontaneous emission. Upon nanosecond photopumping, the waveguides have shown a small-signal gain ...
A novel scanning probe micoscopy study of the (110) surface of rutile titanium dioxide
(Trinity College (Dublin, Ireland). School of Physics, 2008)
This work describes the application of a novel multi-parameter scanning probe technique
to the study of a model semiconductor and a metal oxide surface. Our novel
scanning probe technique enables the simultaneous measurement ...
Thermo and electro-optical analysis of polymer dispersed liquid crystal systems
(Trinity College (Dublin, Ireland). School of Physics, 2002)
The objective of the work performed in this thesis is to prepare Polymer Dispersed Liquid
Crystal (PDLC) systems under optimised preparation conditions and with improved liquid crystal/polymer composition for thermo-and ...
Issues relating to the application of monolithic tuneable laser diodes to multi-species gas detection
(Trinity College (Dublin, Ireland). School of Physics, 2005)
Tuneable Diode Laser Absorption Spectroscopy (TDLAS) technology for gas sensing
has had reliance on, and has benefited from, devices developed for the optical
communications sector, namely distributed feedback laser diodes. ...
Molecular engineering of conjugated organic molecule and carbon nanotube assemblies - a linear and nonlinear spectroscopic study
(Trinity College (Dublin, Ireland). School of Physics, 2007)
Single walled carbon nanotubes (SWNTs) possess unique structural, mechanical
and electronic properties, and are thus promising materials for a host of future applications.
However, their potential is limited in that they ...
Investigation of near-infrared laser diodes for application in space-based spectroscopic gas sensing
(Trinity College (Dublin, Ireland). School of Physics, 2007)
The availability of numerous semiconductor diode lasers that provide wavelength
tuneable, high output power, single frequency emission in the near infrared region of the
spectrum (0.7μm - 2.5μm) provides researchers with ...
Ultrafast non-linear optics for telecommunication applications
(Trinity College (Dublin, Ireland). School of Physics, 2003)
The aim of the research done for this thesis was to characterise the properties of a fibre
laser producing ultrashort pulses at the telecommunication wavelength of 1550nm. We also
measured the nonlinear optical properties ...
Generation, characterisation and solidification of crystalline microfoams
(Trinity College (Dublin, Ireland). School of Physics, 2008)
This study is centered around the spontaneous ordering of equally sized microbubbles on
top of a liquid pool, forming wet crystalline microfoams. This type of ordering was firstly
observed by Bragg and Nye in 1947 and only ...
Numerical investigations of magnetic field effects on electrodeposition
(Trinity College (Dublin, Ireland). School of Physics, 2002)
Electrodeposits are fractal in nature when grown in a flat electrochemical cell, in which an aqueous solution of salt of a metal such as Cu, Zn or Ag is held between an anode and cathode by two flat sheets of perspex. These ...
Design and fabrication of a waveguiding organic double heterostructure light-emitting device : a milestone in the development of an electrically pumped polymer laser
(Trinity College (Dublin, Ireland). School of Physics, 2003)
The development of an electrically pumped polymer laser fabricated using simple solution processing would revolutionise the optial data storage and communications industry. In order to achieve this, a research strategy, ...
