"opposing channels cause light beams to interfere with each other in stadium cavity... adjusting relative intensity and delay of light beams entering the 2 channels altered radiation pattern outside cavity... certain frequencies can support 2 independent, overlapping RSMs, which cause all light to enter stadium cavity without reflections back to channel ports, enabling better storage, routing, and control of light signals... energy harvesting, computation, communications, and biomedical sensing"
