The effectiveness of scanning and steering functionalities of the optical phased array (OPA) based LiDAR implementations rely heavily on the design intent-based correct-by-construction layout of arrayed waveguide delay lines. Manual implementation using a series of low-loss bends and waveguide segments with sequentially altered optical path lengths across all the channels to guarantee successive length (and phase) difference between adjacent channels is a recipe destined for low yield.

Watch our demonstration to learn how we used ÁùºÏ²ÊÖ±²¥¿ª½± OptoCompiler advanced python-based design automation capabilities to achieving the desired optical phase difference requirements of a LiDAR phase array while managing output power across the emitter array.

Agenda: 

• Introduction to LiDAR technology, focusing on the challenge of controlling the phase of light in the photonic phase array for beam steering

• Introduction to ÁùºÏ²ÊÖ±²¥¿ª½±' photonic design tools, emphasizing the tools used in the demo

• Complete demo of ÁùºÏ²ÊÖ±²¥¿ª½± photonic design tools, including schematic and partially finished layout, waveguide creation with precise length control, addition of user-defined components, and simulation results
