“…Optical microring resonators have been applied in various devices and fields, such as sensor technology, including pressure sensors (Seyfari et al, 2020), thermal sensors (Zhu & Lou, 2020), gas sensors (Koushik & Malathi, 2020), and chemical sensors (Bavili et al, 2020). Microring has also been applied as a modulator (Moradi et al, 2021) and an optical switch Singh et al, 2021) due to its compact size (Biswas et al, 2021), high compatibility (Bogaerts et al, 2012), low cost (Kim et al, 2013), and utilization of evanescence field that makes it immune towards electromagnetic disturbances (Bogaerts et al, 2012).…”
