  • CREOL Fall Colloquium: Mikael Rechtsman, Penn State University

    CREOL: 102 and Virtual

    Mikael RechtsmanPhysics Department, Penn State University Tile: Two experiments on aperiodic photonic crystals Abstract: Photonic crystals -- transparent periodic dielectric structures -- have been called "semiconductors for light" in the sense that photons propagate through them much as electrons propagate through crystalline solids.  In the first part of my talk, I will show how straining a photonic crystal can make photons …

  • SEMINAR: Breaking the Volume Barrier in Mid-IR Photonics: From Specialized Sensors to Scalable Semiconductor Integration

    CREOL: 102 and Virtual

    Abstract: The Mid-Infrared (Mid-IR, 2–20 µm) spectral range holds immense promise for high-precision gas sensing, semiconductor metrology, environmental monitoring, and industrial IoT due to the distinct molecular "fingerprint" absorption bands located in this region. Despite its transformative potential, widespread commercial adoption of Mid-IR photonic devices has historically been constrained by fundamental industry barriers: high manufacturing costs, complex III-V and II-VI …
