- Design of a programmable photonic integrated circuit based on carrier depletion phase shiftersPublication . Velázquez, Ernesto Lazaro Chavez; Lourenço, Paulo Jorge Passos Sério; Fantoni, AlessandroAbstract Photonic integrated circuits (PICs) have appeared in response to current technological challenges such as increased speed, demand for greater bandwidth and processing capacity, especially for applications that require extremely fast, high-performance data processing that Integrated Circuits (ICs) cannot satisfy. The range of applications for this technology includes ultra-fast data centers, optical communications, biosensors, sensors for vehicles, quantum processors, and Artificial Intelligence (AI). As this technology continues to advance, there is a growing academic and scientific need to contribute to technology, which in turn opens new market opportunities. In this work, we will analyze the main optoelectronic properties of the materials used for PIC design and the latest advances in waveguide and coupler topologies, focusing on hydrogenated amorphous silicon (a-Si:H) as the main material and directional couplers as the main structure. An architecture will be proposed that looks to respond to problems in conventional directional couplers. It is also intended to use this new coupler design to create a programmable circuit that can be controlled by the Thermo-Optic Effect (TOE) and the Carrier Depletion Phenomenon (CDP). The methodology used integrates the most recent and classic studies of the mathematical and physical principles that govern these structures and materials, using analysis tools such as MATLAB and Python, with the aim of laying the theoretical foundations for the use of professional design tools. in our case, we will use Synopsys' Rsoft-CAD Layout, which implements advanced algorithms such as: Finite Difference Time Domain (FDTD), Beam Propagation Method (BPM), and Finite Element Method (FEM). In conclusion, a document will be presented that has the relevant theory of PICs and their control methods, as well as two functional solutions and their applications.
