Summary We report the first waveguide-coupled round-corner octagonal microresonator channel add-drop filters on silicon-nitride-on-silica substrates. By using photolithography and plasma etching, we fabricated a waveguide-coupled 50-micron sized octagonal microresonator with 15-micron radius round corners. Our experiment reveals TM-polarized whispering-gallery-like modes with a Q of about 3800 and a finesse of 18.
