Abstract
Photonic integration is an appealing technology for emerging applications in communications, medical diagnostics and sensing. Silicon Photonics presents a highly attractive solution for large-scale photonic integration, principally because it is based on well-established CMOS-fabrication technologies. However, Silicon photonics can be difficult and expensive to implement, as it requires complex device design, fabrication and packaging capabilities. Photonic Libraries And Technology for Manufacturing (PLAT4M) is a major European project that brings together the key capabilities required to develop solutions for a range of Silicon photonic-based applications. This paper will present an overview of the PLAT4M project. It will present, in detail, a key application demonstrator (Coherent Beam Combiner), highlighting the ability of the project team to develop an integrated Silicon Photonic sub-system, from design, through to device fabrication, packaging and final test. The paper also highlights the need to consider additional capabilities besides device fabrication, such as packaging, which are critical to achieving fully operational sub-systems.
Highlights
The PLAT4M (Photonic Libraries And Technology for Manufacturing) project focuses on bringing the existing silicon photonics research platform to a level that enables transition to industry, suitable for different application fields and levels of production volume
In the following we present, in detail, the workflow of the silicon photonic chip for the coherent beam combining application which is a key application driver in the PLAT4M project
We present each critical stage of the development chain: motivation for the application, photonic chip design and fabrication, photonic packaging, test and characterisation
Summary
The PLAT4M (Photonic Libraries And Technology for Manufacturing) project focuses on bringing the existing silicon photonics research platform to a level that enables transition to industry, suitable for different application fields and levels of production volume. 15 European R&D institutes and CMOS companies, key industrial and research organizations in design and packaging, as well as end users in different application fields to build the complete supply chain. Upgrading existing photonic platforms to become compatible with industrialization is mandatory at this point. It requires the establishment of design and process flows by taking into account design robustness, process variability and integration constraints. The PLAT4M partners bring a critical combination of expertise to the challenge of building a complete supply chain for commercializing silicon photonics in Europe
