Cryogenic packaging for scalable hybrid quantum PICs
(Optica Publishing Group, 2024) Bernson, Robert; Witte, Alexander; Clark, Genevieve; Gradkowski, Kamil; Saha, Matthew; Leenheer, Andrew; Chen, Kevin; Gilbert, Gerald; Eichenfield, Matt; Englund, Dirk; O’Brien, Peter
We demonstrate a robust packaging method for PICs using surface grating couplers. We use this method to create diamond color center quantum memory modules with active photon routing, strain tuning, and operation to millikelvin temperatures.
Microneedle electrodes: materials, fabrication methods, and electrophysiological signal monitoring-narrative review
(Springer Nature, 2025) Singh, Om Prakash; El-Badawy, Ismail M.; Sundaram, Sornambikai; O'Mahony, Conor; Higher Education Authority; Science Foundation Ireland; European Regional Development Fund
Flexible, microneedle-based electrodes offer an innovative solution for high-quality physiological signal monitoring, reducing the need for complex algorithms and hardware, thus streamlining health assessments, and enabling earlier disease detection. These electrodes are particularly promising for improving patient outcomes by providing more accurate, reliable, and long-term electrophysiological data, but their clinical adoption is hindered by the limited availability of large-scale population testing. This review examines the key advantages of flexible microneedle electrodes, including their ability to conform to the skin, enhance skin-electrode contact, reduce discomfort, and deliver superior signal fidelity. The mechanical and electrical properties of these electrodes are thoroughly explored, focusing on critical aspects like fracture force, skin penetration efficiency, and impedance measurements. Their applications in capturing electrophysiological signals such as ECG, EMG, and EEG are also highlighted, demonstrating their potential in clinical scenarios. Finally, the review outlines future research directions, emphasizing the importance of further studies to enhance the clinical and consumer use of flexible microneedle electrodes in medical diagnostics.
Fabry-Pérot cavity in SiN for non-linear applications
(Optica Publishing Group, 2024-12) Monopoli, Davide; Calò, Giovanna; D’Orazio, Antonella; Wall, Jack; Badri, S. Hadi; O’Faolain, Liam; Devarapua, G. C. R.; Science Foundation Ireland; Pilot Photonics
We present side-coupling Fabry-Pérot-based resonant mirror cavities in the 800 nm thick silicon nitride platform, implementing tapered and conventional Bragg grating. Experimental results highlight enhanced Q-factors and tunability, crucial for femtosecond hybrid laser generation.
Kilcrea Friary: Franciscan heritage in County Cork
(Tower Books, 1999) Maher, Denise; Dúchas; Fás; West Cork LEADER Co-operative Society Ltd
The ruins of Kilcrea friary stand as a monument to its glorious past. This was a past full oflearning, Christianity and Franciscan life. The friary's architecture is a reminder of a very different time and culture and its history is one of turbulence and sadness resulting in its eventual destruction. With the passing of the centuries its history has begun to fade and consequently there is a risk that this will be completely lost for future generations. Being mindful of this, the Bride Valley Community Association commissioned this book on Kilcrea friary. It provides an understanding of Medieval Franciscan life and architecture of the time and of how Kilcrea friary formed an important part of this. As we enter both a new century and a new millennium, the preservation and retention of the history of the friary becomes even more important. It is expected that the next millennium will provide technological advances so great that they cannot even be imagined at present. Hopefully - this publication on Kilcrea friary will remind future generations of the local community of its heritage - full of history, culture, hope and expectations just as it is hoped the new millennium will be. It may serve as a link with the past.
