Thin-film lithium niobate (TFLN) has emerged as a versatile platform for phononic and photonic devices with applications ranging from classical signal processing to quantum technol…
Reconfigurable inverse designed phase-change photonics
Changming Wu, Ziyu Jiao, Haoqin Deng +5
Chalcogenide phase-change materials (PCMs) offer a promising approach to programmable photonics thanks to their nonvolatile, reversible phase transitions and high refractive index…
Freeform Direct-write and Rewritable Photonic Integrated Circuits in Phase-Change Thin Films
Changming Wu, Haoqin Deng, Yi-Siou Huang +4
Photonic integrated circuits (PICs) with rapid prototyping and reprogramming capabilities promise revolutionary impacts on a plethora of photonic technologies. Here, we report dire…
Extremum seeking control of quantum gates
Erfan Abbasgholinejad, Haoqin Deng, John Gamble +4
To be useful for quantum computation, gate operations must be maintained at high fidelities over long periods of time. In addition to decoherence, slow drifts in control hardware l…
