This project will investigate two scanning optical methods capable of obtaining improved lateral resolution in surface plasmon microscopy.The first method will use a pump beam to perturb the local refractive index of the sample, and thus couple light into a surface plasmon mode. A second beam will force leakage of the beam at fixed point therefore ensuring that the plasmon passes through a well defined path. Its passage will therefore depend on the optical configuration rather than the decay of the wave. This technique will allow coupling from a vacuum unlike existing techniques.A second method will examine the reflectance of the sample in the back focal plane. This will involve excitation of the sample over an annulus, so providing a two dimensional focus for the surface plasmons. The lateral resolution of the microscope operating in this mode will be determined by the wavelength of the wavemode rather than the decay length. If the work in this proposal is successful it will be used to pump prime a larger research programme. Dr Velinov is clearly an ideal person to carry out this early work because of his experience with the experimental apparatus and also his knowledge of solid state and thermal physics.
