This work aim to determine a Single Mode (SM) Silicon-On-Insulator (SOI) rib waveguide using Machine learning (ML) techniques, which learn automatically by matching the input data with the target property. Random Forest (RF) is the ML algorithm used in this work. The accuracy of the model reaches 99% by using R2 score. The device is a rib waveguide based on Silicon (Si), with a cladding made of Silica (SiO2) . The results obtained illustrate the conditions for SM, with the width and the rib etch-depth found to be relatively smaller compared to the total thickness. The ML approach have proven to be quick and effective regarding this problem.  \n1 Introduction  \nWaveguides are the fundamental building block for Photonic Integrated Circuits (PICs), allowing to guide, confine and modulate the electromagnetic signal [1] . Therefore, due to the important role of the waveguides, many researchers have investigated different waveguide parameters to achieve adequate proprieties for photonic applications. However, many of these works adopt, or aim to design, Single Mode (SM) waveguides, which is an important and crucial property to reduce modal dispersion and prevent the excitation of higher-order modes. These works rely on different methods and techniques to determine the conditions for SM. For instance, R.A. Soref[et. al](et. al) investigate the SM conditions by using Modematching and Beam-propagation methods [2] . These conditions depend on optimization of two coefficients, namely the ratio (H-h)/H in Fig. 1, and a pure number named 􀟙 [2], which have both received several tunings over the years. For example, Pogossian et al. found different values of these coefficients compared to Soref work [3]. Another common method to find SM is by using complex numerical techniques such as finite element method. However, these methods are time consuming and require high computational resources.  \nIn this work, we develop a Machine Learning (ML) model using Random Forest algorithm to determine the SM property for a rib waveguide based on the same geometry of Fig. 1. The ML approach provides a quick estimation of the concerned property by mapping the input to the output and form a general function approximation. This approach is considered much simpler and quicker than the methods discussed above.  \n2 Dataset Construction  \nThe type of waveguide used in this work is shown on Fig.  \n1.
