Binary square axicon with chiral focusing properties for optical trapping
Balasubramani Vinoth, Anand Vijayakumar, Mani Ratnam Rai +4
We introduce a novel phase-only diffractive optical element called chiral binary square axicon (CBSA). The CBSA is designed by linearly rotating the square half-period zones of the…
