Controlled modulation of optical energy in the high order Hermite-Gaussian laser modes
Hemant Kumar Meena, Brijesh Kumar Singh
The multiple lobes of high order Hermite-Gaussian (HG) laser modes differ in terms of shape, size, and optical energy distribution. Here, we introduce a generic numerical method th…

Particle manipulation beyond the diffraction limit using structured super-oscillating light beams
Brijesh Kumar Singh, Harel Nagar, Yael Roichman +1
The diffraction limited resolution of light focused by a lens was derived in 1873 by Ernst Abbe. Later in 1952, a method to reach sub-diffraction light spots was proposed by modula…
