Optical vortex array in spatially varying lattice
Amit Kapoor, Manish Kumar, P. Senthilkumaran +1
We present an experimental method based on a modified multiple beam interference approach to generate an optical vortex array arranged in a spatially varying lattice. This method i…

Embedding a nondiffracting defect site in helical lattice wave-field by optical phase engineering
Manish Kumar, Joby Joseph
We present a technique to optically induce a defect site in helical lattice wave-field where the combined wave-field continues to maintain its nondiffracting (ND) nature. This is d…

Digitally reconfigurable complex 2D Dual lattice structure by optical phase engineering
Manish Kumar, Joby Joseph
We present a method to combine two periodic lattice wave-fields to generate a complex dual lattice wave-field which could be employed for microfabrication of corresponding 2D dual…
