Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Micro-ring resonators (MRRs) have emerged as vital components in photonic applications, offering precise control of light at the nanoscale. Achieving optimal MRR design parameters is crucial for maximizing their performance in high-speed applications. This study aims to employ feature engineering and supervised machine learning (ML) techniques to comprehensively analyze MRRs. This includes impact of change in MRR design geometries, such as radius, coupling geometry, waveguide properties to key MRR output parameters, including the quality factor, full width at half maximum (FWHM), rise/fall time, and free spectral range (FSR). By utilizing results of over 1000 simulations in Lumerical, as well as incorporating the theoretical knowledge of MRRs, the study seeks to build highly accurate predictive model.
