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.Item FPGA-programmable 512 Gbps 2.5D DWDM photonic network interface card(Institute of Electrical and Electronics Engineers (IEEE), 2024-10-29) Robinson, James; Hattink, Maarten; Dai, Liang Yuan; Haimowitz, Max; Li, Mao; Jang, Daniel; Morrissey, Padraic; Kumar Malik, Arun; O’Brien, Peter; Robertson, Seth; Seok, Mingoo; Bergman, Keren; Defense Advanced Research Projects Agency; U.S. Department of EnergyWe present a 2.5D integrated, FPGA-programmable silicon photonic network interface card implementing a bidirectional 512Gbps dense wavelength-division multiplexed link. We demonstrate sixteen transmitter and eight of sixteen receiver channels operating error-free at 16 Gbps each.Item Refractive index sensing using the optical heterodyne method and photonic crystal hybrid laser(Optica Publishing Group, 2024) Horizon 2020; Science Foundation IrelandWe have demonstrated a new approach to refractive index sensing based on the optical heterodyne method and a refractive index sensitive hybrid laser. We achieved over an order of magnitude improvement in the detection limit relative to the RI measurement based on a passive optical resonator.
