Reliability Assurance of Photonic Integrated Circuit (PIC) Based Devices Used in Aerospace Applications
This document is intended to provide reliability assurance recommended practices for the deployment of individual photonic devices and PIC-based devices into aerospace platforms, focusing on reliability requirements to reach Technology Readiness Level (TRL) 7, 8 and 9. It will cover reliability assurance tests for single element and PIC chips, packaged single element and PIC chips and some single element and PIC based higher functionality modules, such as fiber-optic transmitters and receivers, free space optical transmitters and receivers, illuminators and sources for optical sensors. The document will provide the reasons and methods for aerospace reliability assurance of PIC chips, PIC based packages and PIC based devices. It will be as inclusive as possible, including PIC chips fabricated in the main material systems: semiconductors (Group IV, III-V, II-VI), electro-optic crystals (lithium niobate) and polymers. The document will also include the main types of packages and the most relevant PIC based devices.
Rationale: Photonic Integrated Circuit (PIC) technology has made significant advancements in the recent past, leading to opto-electronic products with novel or significantly enhanced functionality. These new devices relate to many areas of aerospace platforms, such as intra-vehicle fiber optic communications, inter-vehicle free space optical communications, infrared illumination, lidar, gyroscopes and other sensors. Common practices for reliability assurance of these PIC semiconductor chips and opto-electronic devices based on them have not been developed yet and there is a strong need to develop these recommended practices for aerospace applications. Such a document will strongly support the transition and insertion of these advanced photonic components into aerospace platforms. In addition, there is still a need to document aerospace requirements for reliability assurance of individual photonic components.
