"synthetic dimension on a silicon ring resonator, using the same approach used to build complementary metal-oxide-semiconductors (CMOS)... particular bandwidths... acquired a “comb-like” optical spectra... While the developed device comprises one ring, more could be stacked to cascade effects and quickly characterize optical frequency signals... smaller and compact than previous approaches, which employed optical fibers connected to various components"
