Presentation: Lucem sequimur: Light-matter interaction from the photon perspectiveLight is more than a tool for perception - it is the fundamental medium through which we interrogate the physical world, from nanometric structures to the farthest reaches of the cosmos. It also underpins much of modern technology, from global telecommunications and biomedical imaging to emerging optical and photonic computing architectures. In …
CREOL CalendarMikael 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 …
CREOL CalendarAbstract: 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 …
