description | Convolutional neural network (CNN) models consist of CNN block(s) and dense neural network (DNN) block(s) are used to perform image classification on beam profiles in light beam coupled out from silicon photonics (SiPh) mixed pitch gratings. The beam profiles are first simulated and segregated into 3 categories based on their corresponding height above the SiPh gratings. With 1 CNN block, 1 DNN block, and 128 nodes in the DNN block, classification accuracy of 98.68% is achieved when classifying 454 beam profile images to their corresponding categories. Expanding the number of CNN blocks, DNN blocks, and the number of nodes, 64 CNN models are constructed, trained, and evaluated. Out of the 64 CNN models, 52 of them achieved classification accuracy of >95%. |
