Left and Right Direction of Optical Signals

Caption

These images, taken with a near-field scanning optical microscope, show plasmonic waves propagating across the surface of the coupler. In the central image, linearly polarized light is captured and converted into waves that travel both left and right. In the left image, left-hand circularly polarized light is routed only to the left; in the right image, right-hand circularly polarized light is routed only to the right.
