Summary on Grant Application Form
By engineering structures having at least one dimension similar to the wavelength of light, it is possible to create devices which control the interaction of light with matter. Such structures can be realised by fabricating multilayer structures that act as resonant cavities for photons. By placing an organic semiconductor within the cavity, it is possible to create entirely new states which are admixtures of the photon and the excited state of the organic molecule. This effectively allows a control over the physical processes that influence spontaneous emission. I will investigate such structures and attempt to create new low-threshold lasers and other hybrid organic-inorganic semiconductor devices. I will also use a scanning near-field optical microscope to develop new lithography protocols to produce photonic crystals. Photonic crystals are structures where laterally patterned microstructured arrays control the range of propagation energies of a photon. Such materials would have considerable technological application in the creation of computers and communication systems that process information using light. Finally I will investigate how molecular interactions naturally occurring within organic thin films affect their flourescence properties. Understanding such processes will be important in designing new efficient materials for use in display technologies.
