    "abstract": "A chirality-based approach to making a one-way waveguide that can be used as\nan optical isolator or a polarizer is described. The waveguide is rectangular,\nand chirality is introduced by making slanted rectangular grooves on the\nwaveguide walls. Chirality of the waveguide manifests as a strong circular\ndichroism, and is responsible for transmitting one circular polarization of\nlight and reflecting the other. Optical isolation of the propagating circular\npolarization is accomplished when the chiral waveguide is placed in front of a\nnon-chiral optical device. Even the crudest implementations of chirality are\nshown to exhibit significant circular dichroism.",
