    (a) Optical microscope image of the fabricated microring. (b) Magnified scanning-electron-microscope (SEM) image of the fabricated microring. (c) The SEM image shows that a small slit is cut through the microring with a focused ion beam. (d) The optical microscope image of the ridge waveguide on other LNOI chips for coupling of the microring.
