ABSTRACT: High performance thermal imagers are increasingly tasked with providing more information to downstream user electronics at even faster speeds in an effort to do more with traditional scene and target information. Additionally, infrared sensors are moving towards multi-use capability, meaning a single sensor is now tasked with simultaneously performing the requirements of a collection of past camera systems. In order to deliver on requirements such as field of view, resolution, and frame rate, focal plan arrays (FPAs) and digital read-out integrated circuits (ROICs) are being asked to generate, move, and process massive data outputs across parallel outputs currently running over electrical wire. To meet increasing data rate demands, conversion of digital pixel data to optical-out data transmission using photonic elements is being explored to provide data management solutions for future sensors with excellent energy efficiency. Photonic integrated circuits are gradually becoming more commonplace on foundry process lines, which opens the door to design and develop alongside stacked ROIC technologies. Although photonics data transmission has matured significantly in the telecom industry, harnessing this capability in the cryogenic environment of a FPA remains a challenge. This talk will outline the increasing need to provide more data at less energy per bit, the potential formats to implement optical modulation, and the challenges associated with maturing a cryogenic optical-link for future thermal sensor technologies.
