    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.

    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.

    Evanescent wave quartz-enhanced photoacoustic spectroscopy employing dielectric coated side-polished fibers for sensing applications
    (Optica Publishing Group, 2024-12) Twomey, Cian F.; Biagi, Gabriele; Ruth, Albert A.; Ali, Farhan; Di Falco, Andrea; O’Faolain, Liam; Walsh, Anton
    We present an all-fiber laser gas analyzer using quartz-enhanced photoacoustic spectroscopy, featuring a dielectric-coated side-polished fiber, custom quartz tuning fork, and acoustic micro-resonators, achieving over 42 times enhancement in QEPAS signal for improved detection performance.

    Analysis of the optical coupling between 2.3 μm GaSb diode lasers and passive waveguides for monolithic integration on Si platforms
    (Institute of Electrical and Electronics Engineers (IEEE), 2022-12-14) Paparella, Michele; Monge Barlome, Laura; Rodriguez, Jean Baptiste; Cerutti, Laurent; Grande, Marco; O'Faolain, Liam; Tournie, Eric; Horizon 2020; Agence Nationale de la Recherche
    Although discrete lasers grown on silicon have been demonstrated, light coupling into on-chip passive waveguides remains to be properly studied. We investigate theoretically the optical coupling between 2.3 μm GaSb-based diode lasers (DLs) epitaxially grown on a Silicon photonic chip and the passive waveguides.

    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 2020
    Interest 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.
