Photonic Crystal Resonator (IMAGE) Optica Caption Researchers demonstrated a silicon-based optical communication link that combines two multiplexing technologies to create 40 optical data channels. The ring-shaped photonic crystal resonator (left) features a nanopattern inside (right) that splits a selected resonant mode for comb generation. Images taken with scanning electron microscopy.
