WebApr 9, 2024 · The propagating guided modes by optical waveguides hardly produce optical chirality because of the broken symmetry between electric and magnetic components. Here for the first time we discover that the directional coupling of spatially guided modes can create polarization helicity, and thus generate optical spin and chirality. WebWe demonstrate that the helicity-preserving features of our cavities stem from a spin–orbit coupling mechanism seeded inside the cavities by the specific chiroptical features of planar chirality.
