Joint Plenary Session II

1. Science Diplomacy in the Middle East: Slogan or Reality?

   Presenter: Gihan Kamel, Helwan University, Egypt

    Presentation Details

   Plenary

   Despite the national standards those are pillars to create a state of harmony within any society, one still needs to speak a language that must be unbiased in order to be accepted at least as a midpoint. To some degree, this is the case with science. To some degree, this is the particular case of the Middle East. Transforming repulsion into trust by using science as a new solo player is undoubtedly a huge success. SESAME Members are Cyprus, Egypt, Iran, Israel, Jordan, Pakistan, Palestine and Türkiye. It seeks excellency of science, besides functioning as a bridge of understanding for a community that will be able to deal with scientific challenges, political conflicts, and beyond.Authors: Gihan Kamel, Helwan University

2. A Revolution in High-Q Integrated Photonics

   Presenter: Kerry Vahala, California Institute of Technology, United States

    Presentation Details

   Plenary

   High-Q microresonators provide access to nonlinear optical phenomena at milli-Watt power levels. And the resulting device functions, now in miniature form, are paving the way to integrated optical systems for sensing, metrology, spectroscopy, microwave generation, time keeping and data transmission. Once discrete and reliant upon specialized processing techniques for optical loss reduction, high-Q microresonators are today planar, capable of integration and in some cases fabricated on CMOS foundry lines. After a brief overview of their history and early nonlinear optical demonstrations, Vahala will focus on recent system demonstrations and conclude by considering the future performance limits of high-Q systems.Authors: Kerry Vahala, California Institute of Technology

   We report on a novel way of realizing microfabricated alkali vapor cells for miniature atomic devices. Reminiscent of the well-established glass-blowing techniques, it consists in implementing “make-seal” and “break-seal” features -commonly found in cell filling setups- within microfabricated devices. We show how single-use sealing structures can be laser-actuated, either to hermetically isolate cavities from each other, or to connect them together. We discuss some use cases in atomic devices.Authors: Vincent Maurice, Univ. Lille, CNRS, Centrale Lille, Univ.
