Controllable experimental modulation of high-order Laguerre–Gaussian laser modes

HK Meena, B Pant, BK Singh - JOSA A, 2023 - opg.optica.org
High-order helical and sinusoidal Laguerre–Gaussian (LG) laser modes have uneven
energy distribution among their multiple concentric vortex core rings and lobes, respectively …

Super-resolution imaging system developed from vector superoscillatory field illumination

R Qi, G Gbur - Optics Letters, 2023 - opg.optica.org
Superoscillations are oscillations of a band limited waveform with a local frequency higher
than the bandlimit. Spatial superoscillations show great potential for performing super …

Super-oscillatory spots with different inhomogeneous linear polarized states

B Pant, HK Meena, BK Singh - Applied Optics, 2023 - opg.optica.org
We present the formation of super-oscillatory (SO) spots by tightly focusing the
inhomogeneous linear polarized beam of different polarization states. At the entrance pupil …

Phase-only mask for superoscillatory enhanced resolution in confocal microscopy

I Iglesias, JM Filiu - Optics Express, 2024 - opg.optica.org
In this work, we present a simple phase mask that generates a superoscillatory spot suitable
for confocal scanning microscopy enabling lateral sub-diffraction resolution. When …

Controlling Superoscillation Based Imaging With Polarization and Coherence

R Qi - 2024 - search.proquest.com
Superoscillation is a physical phenomenon, in which the local oscillations of a bandlimited
signal fluctuate faster than the fastest Fourier component of the signal. In recent years …
