WebSep 22, 2024 · By optically trapping the chiral gold nanoparticles, the study team observed the optical gradient force arising from the chirality (i.e., the difference between the gradient force by left- and right-circularly polarized light). The results indicated that the optical gradient force was distinct for particles in the D- and L-forms. WebWe 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 binary square axicon with respect to one another. A quadratic phase mask (QPM) is combined with the CBSA using modulo-2π phase addition technique to bring the far-field …
