Analysis of the Principle and State-of-art Applications of Si-Based Chip on Lidar

Abstract

In recent years, as the feature size of transistors continues to decrease, Moore's Law is also approaching its limits. On this basis, In the post-Moore era, optical interconnect technologies with inherent attributes such as low latency, low power consumption, and low crosstalk have gained widespread attention in the industry. Silicon photonics technology has emerged, leveraging the accumulated knowledge from the silicon-based microelectronics industry over half a century. Optical phased arrays, unlike traditional mechanical-based lidar systems, offer advantages such as small size, low cost, and high accuracy. When combined with mature CMOS processes, they hold significant research value and market prospects. With this in mind, this study will discuss the principle as well as the state-of-art applications for Si-based chip on Lidar. According to the analysis, the current limitations are also demonstrated and suggestions are proposed based on the evaluations. Overall, these results shed light on guiding further exploration of chip developments on Lidar.
