Item Automating photonic systems-in-package assembly for high performance glass interposers(2024) Shortiss, Kevin; Hwang, How Yuan; Parra, Josue; Butler, Sharon; Ghomashi, Mohammadamin; Li, Yanlu; Noell, Wilfried; Seyfried, Moritz; O’Brien, Peter; Horizon 2020Interest in high performance glass interposers has been growing, due to the advantages which have been demonstrated over standard silicon interposers. In this paper, we demonstrate fully automated micro-optics and laser sub-assembly alignment and laser-assisted bonding processes which are compatible with glass interposers.Item A power simulation tool for the optimization of wireless sensor nodes(Institute of Electrical and Electronics Engineers (IEEE), 2024) Asthana, Prateek; Costanza, Mario; Ahern, Eoin.; Flannery, John; Geoghegan, Paul; Ingenito, Andrea; Horizon 2020Optimization of system-level power consumption is key in extending battery-life in IoT Wireless Sensor Network (WSN) nodes. Early power analysis aids designers in making informed choices about components, design architectures, communication protocols, and battery capacity. This is particularly important when using Energy Harvesters (EH) to extend a node’s battery-life or achieve full power autonomy. This work introduces a simulation tool for solar-powered Asset Tracking (AT) WSN nodes developed in the EU project Energy ECS. Using experimental data from partners CSEM and Net Feasa, the tool performs a step-by-step energy balance for an intermodal dry container during shipment, predicting the necessary EH and battery sizes for autonomy, while identifying power-hungry processes to optimize performance.Item Bio-inspired internet of fish towards a climate resilient future(2024) Cheng, Steven MatthewThis essay reports on the utilization of microwave, optical, and acoustic technology in establishing an underwater interconnected network, internet-of-fish (IoF), to provide comprehensive and real-time information on marine quality for climate monitoring and freshwater preservation. In particular, bio-inspired ocean explorers, capable of traversing different levels of the ocean from shallow to deep waters, are incorporated with communication front-ends to allow inter-explorer communication. Additionally, microwave sensors are discussed as complementary sensing to conventional sensors to provide a more comprehensive and cost-effective characterization of water quality. Moreover, wireless charging mechanisms and mmWave and microwave power beaming are also discussed to provide sustainable and efficient power. Data from these explorers are to be transmitted to nearby hovering unmanned aerial vehicles (UAVs) wherein cross-boundary communication methodology is discussed. With the well-established IoF, a deeper understanding of the earth and its climate is achieved leading to adaptation, mitigation, and prevention of further climate degradation.Item Enabling volume-compatible photonic medical devices through hybrid integration assembly(Institute of Electrical and Electronics Engineers (IEEE), 2024-12-20) Patil, C. M.; Hall, Matthew L.; Zaruba, P.; Zoldak, M.; Li, Y.; Aasmul, S.; Morrissey, P. E; O’Brien, P.; Horizon 2020A highly integrated and compact photonic module is realised using state-of-the-art wafer-level assembly processes, paving the way for volume production. This advancement opens new avenues for cost-effective and user-friendly point-of-care medical devices, facilitating early detection of cardiovascular conditions.Item All optically powered chip-on-tip microcamera for surgical guidance(Optica Publishing Group, 2023) Sekar, Sanathana Konugolu Venkata; Baskaran, Meena; Ma, Hui; Rensing, Marc; Gradkowski, Kamil; Khan, Asif; Antony, Cleitus; Townsend, Paul D.; Corbett, Brian; Andersson-engels, StefanWe present an all-optical powered 6 Fr microcamera based chip-on-tip endoscope system. The optical powering is achieved by fiber illuminating a customized multisegmented photovoltaic cell. The powering system produces 10 mW of electrical power sufficient to power microcamera. We demonstrated the performance of the system on calcification tissue-mimicking phantoms.
