Fatemeh Salahshoori and Suat Icli, representing Qu-PIC – Horizon Europe‘s partner Physikalisch-Technische Bundesanstalt, PTB, showcased groundbreaking research at the Annual Meeting of DPG and DPG-Frühjahrstagung (DPG Spring Meeting) of the Atomic, Molecular, Quantum Optics and Photonics Section (SAMOP).
They presented advancements in photonic integrated circuits (PICs) for quantum sensing and ion trapping. As part of the Qu-PIC project, they introduced scalable PIC modules tailored for quantum sensor applications. These modules will feature tunable lasers spanning UV to near-IR, specialized light conditioning systems, and photonic-integrated ion trap chips—key components for future quantum sensors. 𝗔 𝗵𝗶𝗴𝗵𝗹𝗶𝗴𝗵𝘁 was the use of ring resonator couplers and grating out-couplers on an Al₂O₃ platform to optimize light control in ion-trap systems.
Additionally, they unveiled an aluminum nitride (AlN)-based phase modulator designed for precision laser control in ytterbium ion trapping experiments. Operating across a broad wavelength and frequency range, this modulator ensures efficient laser phase and frequency adjustments—essential for ion cooling and state preparation. With an electrical bandwidth of up to 40 GHz, low signal loss, and high modulation efficiency, this platform paves the way for scalable quantum technologies.
These innovations mark significant progress toward the end goals of Qu-PIC – Horizon Europe.
