Abstract
An optical device may include a polarization splitter to split a unidirectional rotary optical beam into a first rotary optical beam having a first polarization state and a second rotary optical beam having a second polarization state. The unidirectional rotary optical beam and the second rotary optical beam may have optical power with a first direction of spatial rotation. The optical device may include a reflective element to reverse a parity of the first rotary optical beam in association with causing optical power of the first rotary optical beam to have a second direction of spatial rotation. The optical device may include a polarization combiner to, after reversal of the parity of the first rotary optical beam, combine the first rotary optical beam and the second rotary optical beam to create a bi-directional rotary optical beam having the first polarization state and the second polarization state.
