Schematic Overview of an Inverse Photonic Design Pipeline for Photonic Glass Core Substrates

A schematic overview of an inverse photonic design pipeline for photonic glass core substrates. It shows how the pipeline takes in the desired output and evaluates an ion exchange process defined by a lithographically applied mask, which results in a concentration profile, which is then converted to a refractive index distribution. This is used to calculate the photonic behavior and is compared to the desired output via a merit function. This is reevaluated iteratively until a desired value of the merit function is reached.
