Remus Nicolaescu

CEO/Co-founder
Pointcloud Inc, USA

Remus Nicolaescu is the Co-founder and CEO of Pointcloud Inc., a San Francisco based startup developing coherent 3D imaging solutions using silicon photonics. In 2017, together with a team at University of Southampton, he co-founded Pointcloud Inc., with the mission to create a versatile three-dimensional imaging platform using silicon photonics integration, that would enable 3D cameras to become as ubiquitous and performant as their 2D counterparts. Prior to Pointcloud he held executive roles with technology companies in the US, Europe and Asia. He started his career at Intel, where he performed pioneering work in silicon photonics: he was part of the team that demonstrated the first >1GHz silicon photonics modulator; he proposed and developed the research leading to the demonstration of optical Raman amplifiers and lasers in silicon photonics. He obtained his Masters and Ph.D. in Physics from University of Bucharest and Texas A&M University respectively, and MBA from INSEAD.

 

Title: Coherent focal plane arrays in silicon photonics, towards high performance 3D Imaging using LIDAR

Accurate 3D imaging is essential for machines to map and interact with the physical world. While numerous 3D imaging technologies exist, each addressing niche applications with varying degrees of success, none have achieved the breadth of applicability and impact that digital image sensors have achieved in the 2D imaging world. A large-scale, two-dimensional focal plane array of coherent detector pixels operating as a light detection and ranging (LiDAR) system could serve as the core of a universal 3D imaging platform. It would enable megapixel resolution, high depth accuracy, immunity to interference from sunlight, as well as the ability to directly measure the velocity of moving objects. This talk will present an overview of architectural implementations of large-scale coherent focal plane arrays, and show results of their operation in a 4D imaging (3D + velocity) system. We will discuss performance characteristics, tradeoffs and design optimization for different applications. Finally, we will discuss future architectural implementations and opportunities for pixel size reduction to enable 10 megapixels and beyond coherent imaging cameras.
