COMPAS: co integration of microelectronics and photonics for air and water sensors

COMPAS的主要目标是开发一个紧凑、廉价和超灵敏的空气和水监测PIC传感平台(PSP)，依靠光源、探测器和电子IC的共集成用于片上信号处理。PIC传感器的原理将基于两个导光模式之间的干涉，其中一个模式与分析物相互作用，另一个作为参考。由此产生的强度变化对空气或溶液中分析物浓度的变化提供了极好的灵敏度。可以在同一设备上放置多个光路，从而在超小型设备中提供多分析物检测。COMPAS围绕这一原理建立了首个完全集成的系统(包括光源、探测器和信号处理)。COMPAS PSP从TRL2开始，以终端用户在相关环境中对空气和水的监测进行TRL5验证结束。该项目将定义传感参数，以验证开发的PIC传感器平台(PSP)在相关环境中的三个用例，以符合欧洲绿色交易的零污染雄心-开发核心光子技术，以实施基于光子的传感。其中包括一种新型的光子IC材料系统(氮化铝)、具有优异温度稳定性和灵敏度的双模波导干涉仪、用于增强传感选择性的新型材料涂层系统、用于提高灵敏度和优化光耦合以便于使用低功率激光二极管的新型模式工程的创新纳米结构亚表面。-开发一种Chiplet方法，将光子传感器与微电子IC和光电探测器以及相干光源共集成。这将结合激光光源和硅基材料中的单片集成光电探测器的异质集成。

The main objective of COMPAS is to develop a compact, inexpensive and ultrasensitive PIC sensing platform (PSP) for air and water monitoring, relying on the co-integration of light source, detectors and electronic IC for on-chip signal processing. The PIC sensor principle will be based on interference between two guided light modes, one of which interacts with analytes and the other being a reference. The resulting intensity changes offers excellent sensitivity to changes in concentration of analytes in air or solution. Multiple light paths can be placed on the same device offering multi-analyte sensing in an ultracompact device. COMPAS builds a first-of-a kind fully integrated system around this principle (including light source, detectors and signal processing). The COMPAS PSP begins at TRL2 and will end with TRL5 validation in relevant environment by end-users towards air and water monitoring. The project will - Define sensing parameters for validating developed PIC Sensor Platform (PSP) towards three use-cases in relevant environments, being in line with the European Green Deal’s zero pollution ambition - Develop core photonic technology for implementing photonic based sensing. These include a novel photonic IC material system (Aliminium Nitride), BiModal waveguide interferometers that show superior temperature stability and sensitivity, novel material coating systems for enhanced sensing selectivity and innovative nano structured metasurfaces for novel mode engineering for increased sensitivity and optimized light coupling to facilitate the use of low power laser diodes. - Develop a Chiplet approach to co-integration of photonic sensor with microelectronic IC and photodetectors, and a coherent light-source. This will combine heterogeneous integration of a laser light source and monolithically integrated photodetector in the silicon base material.
