    FIGURE 1. The two rings shown in this image are microresonators. The microcomb is generated within the bigger ring, formed by a pulse of light (shown here as a red spike/soliton) that recirculates within the cavity forever. The smaller ring helps couple light from a straight waveguide (shown as a straight orange line at the bottom), into the bigger ring. In other words: it acts as impedance matching, which means the soliton is generated more efficiently.
    Researchers improve soliton microcomb efficiency by 10x—and open the door to high-performance lasers for a range of other technologies.
