Journal Article
Somekh, M. G., Shen, H., Chow, T. W. K., & Shen, M. (2020). Virtual optics and sensing of the retrieved complex field in the back focal plane using a constrained defocus algorithm. Optics Express, 28(22), 32777-32792. https://doi.org/10.1364/oe.404573

The reflected back focal plane from a microscope objective is known to provide excellent information of material properties and can be used to analyze the generation of surface plasmons and surface waves in a localized region. Most analysis has conce... Read More about Virtual optics and sensing of the retrieved complex field in the back focal plane using a constrained defocus algorithm.

On-chip plasmonic spin-Hall nanograting for simultaneously detecting phase and polarization singularities (2020)
Journal Article
Feng, F., Si, G., Min, C., Yuan, X., & Somekh, M. (2020). On-chip plasmonic spin-Hall nanograting for simultaneously detecting phase and polarization singularities. Light: Science and Applications, 9(1), Article 95. https://doi.org/10.1038/s41377-020-0330-z

Phase and polarization singularities are important degrees of freedom for electromagnetic field manipulation. Detecting these singularities is essential for modern optics, but it is still a challenge, especially in integrated optical systems. In this...

Defocus leakage radiation microscopy for single shot surface plasmon measurement (2020)
Journal Article
Chow, T. W. K., Lun, D. P. K., Pechprasarn, S., & Somekh, M. G. (2020). Defocus leakage radiation microscopy for single shot surface plasmon measurement. Measurement Science and Technology, 31(7), Article 075401. https://doi.org/10.1088/1361-6501/ab7def

Measurement of surface plasmon and surface wave propagation is important for the operation and characterization of sensors and microscope systems. One challenge is to perform these measurements both quickly and with good spatial resolution without an...
