Abstract:Artificial neural network has been introduced to design optical fiber direction couplers.The coupling length and coupling ratio are defined as input and output respectively,which are used to train the neural network model.The radial basis function neural network model is built for optical fiber direction couplers,which are in turn simulated and designed through the model.The results show that this method has the advantages of speediness,accuracy and reliability,which are identified by the design example.In addition,this way, as a novel design approach, can save the cost of device design and decrease period of design.It can be used to design other kind of optical passive device.
Keywords:neural network  coupler  coupling ratio  simulation
