Development of a process design kit for transparent materials

Using Synopsys® Software Suite, we developed a Process Design Kit (PDK) targeting the commercial software OptSim Circuit® for the design of integrated photonics devices on transparent materials. We combined the physical properties and optical parameters of the material from laser direct writing (LDW) experimental data in the literature with theoretical model to carry out numerical Finite Differences Time Domain and Beam Propagation Method simulations. The final PDK includes the main building blocks library, namely straight and bent waveguides, directional coupler, splitter, and mode-converter, which give the opportunity to easily design and simulate more complete layouts, simplifying the creation of complex photonic integrated circuits on transparent materials.
