Due to cost, scalability, performance, and energy efficiency, photonic sensors and transceivers are vital components of data security, communication, and environmental detection.
Integrated photonics technology and electrical systems are a significant part of 5G, autonomous vehicles, and the internet of things (IoT). An everyday example is a fiber optic connector utilized in small form-factor pluggable (SFP) transceivers for data centers and 5G applications. This communication device leverages light to transmit data over optical fibers between the electronic systems.
The engineers require simulation tools to model this and other integrated photonic systems to guarantee that the photonic emitters/detectors are compatible, data transmission is optimized for speed, accuracy, and energy efficiency, and the operation is robust over a range of environmental conditions. They can then incorporate these models to validate, optimize and design the entire system.
A Theoretical Integrated Photonics Workflow for Lidar Systems Design
The user interface (UI) provides an integrated design environment (IDE) that can identify a couple of models, including optical, emissive, thermal, electrical, and electromagnetic simulations. This multiphysics mindset fits the needs of those working on integrated photonics for 5G, autonomous vehicles, and IoT applications.
As an illustration, autonomous vehicles need low-cost lidar system sensors within their environmental detection systems. Using unified photonic simulations, engineers can assess the emitting layer's performance, and the nanoscale integrated phased array is utilized to form the beam.
Generation of the laser beam and its environment interaction is then created through macroscopic optical simulation technology. Then, engineers can then employ Lumerical technology to model how the integrated sensor receives the laser signal calculated from the macroscopic visual simulation.
When simulating lidar systems, the users must acquire integrated photonic information from measurements or vendors. By combining these simulation technologies, engineers will create high-fidelity simulations that allow them to optimize source and detector designs.
To support the engineers who simulate electronic systems and their interaction with photonic circuits, Lumerical has partnerships with different foundries to provide customers with high-quality photonic process design kits (PDKs). Therefore, engineers can simulate and characterize a full electro-optical communication or sensing system by integrating their portfolio with the platform.
