In this paper, we present a direct method to measure surface wave attenuation arising from both ohmic and coupling losses using our recently developed phase spatial light modulator (phase-SLM) based confocal surface plasmon microscope. The measuremen... Read More about Application of confocal surface wave microscope to self-calibrated attenuation coefficient measurement by Goos-Hänchen phase shift modulation.

Sensitive detection of voltage transients using differential intensity surface plasmon resonance system (2017)
Journal Article
Abayzeed, S. A., Smith, R. J., Webb, K. F., Somekh, M. G., & See, C. W. (2017). Sensitive detection of voltage transients using differential intensity surface plasmon resonance system. Optics Express, 25(25), 31552-31567. https://doi.org/10.1364/OE.25.031552

This paper describes theoretical and experimental study of the fundamentals of using surface plasmon resonance (SPR) for label-free detection of voltage. Plasmonic voltage sensing relies on the capacitive properties of metal-electrolyte interface tha...

Ultrastable embedded surface plasmon confocal interferometry (2014)
Journal Article
Pechprasarn, S., Zhang, B., Albutt, D., Zhang, J., & Somekh, M. (2014). Ultrastable embedded surface plasmon confocal interferometry. Light: Science and Applications, 3(7), Article e187. https://doi.org/10.1038/lsa.2014.68

As disease diagnosis becomes more sophisticated, there is a requirement to measure small numbers of molecules attached to, for instance, an antibody. This requires a sensor capable not only of high sensitivity but also the ability to make measurement... Read More about Ultrastable embedded surface plasmon confocal interferometry.

Surface plasmon microscopic sensing with beam profile modulation (2012)
Journal Article
Zhang, B., Pechprasarn, S., & Somekh, M. G. (2012). Surface plasmon microscopic sensing with beam profile modulation. Optics Express, 20(27), https://doi.org/10.1364/OE.20.028039

Surface Plasmon microscopy enables measurement of local refractive index on a far finer scale than prism based systems. An interferometric or confocal system gives the so-called V(z) curve when the sample is scanned axially, which gives a measure of...

Confocal surface plasmon microscopy with pupil function engineering (2012)
Journal Article
Zhang, B., Pechprasarn, S., Zhang, J., & Somekh, M. G. (2012). Confocal surface plasmon microscopy with pupil function engineering. Optics Express, 20(7), https://doi.org/10.1364/OE.20.007388

Surface Plasmon microscopy can measure local changes of refractive index on the micron scale. Interferometric plasmon imaging delivers quantitative high spatial resolution sensitive to refractive index. In addition the so called V(z) method allows im...
