In this paper, generation of the Dammann grating by using the spatial light modulator (SLM) is discussed, and quality of the grating is examined by using the polarization interferometer and Fourier fringe analysis technique.
An ultra-stable high performance SPR sensor based on graphene on Ag configuration is proposed. The proposed sensor shows enhanced performance as compared to widely reported Au on Ag configuration.
The evolution of chain of uni-polar vortices in propagation of Helico-Conical beam plays an important role in shaping the helical amplitude profile in focal volume. This evolution is compared with that of fractional vortex beam.
