“…The characteristic frequency spectrum of the microring, which is dependent upon its size, is a defining factor in the transmission of a selected wavelength of light into another waveguide. The microring resonators are widely employed in the design and manufacture of optical filters [4][5][6], modulators [7,8], optical switches [9,10], optical delay lines [11], and Kerr frequency combs [12][13][14][15], etc. Multiple material systems have been used to fabricate microring resonators, such as silicon on insulator (SOI) [1,[16][17][18], silicon nitride (SiN) [5,19], and lithium niobate on insulator (LNOI) [20][21][22][23].…”
