MID/QC Applied Substrate Series 8 - Coherence Aligned Waveguides: Rethinking Fiber, Photonics, and On Chip Optical Routing

Classical waveguides are designed around refractive index contrast and geometric confinement. In the MID/QC framework, waveguides are reinterpreted as coherence‑aligned channels within the quantized substrate. This paper develops the substrate‑first model in which optical routing emerges from tension‑guided coherence propagation, alignment fields, and ...

Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2

Advanced Materials, EarlyView.
Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...

Metal Oxide Nano‐Interface Boosting the Deep Ultraviolet Adjustable Noise‐Filtering In‐Sensor Computing

Advanced Materials, EarlyView.
We show that sol‐gel‐fractured indium–magnesium oxide combines deep‐ultraviolet responsivity, high carrier mobility, and an excellent memory dynamic range. This unique materials platform enables deep‐ultraviolet long‐afterglow light‐emitting devices with multifunctional integration.

A High‐Resolution THz‐PCF Sensing Framework: Precise Identification of Food Preservatives Through Refractive Index Analysis

Advanced Materials Interfaces, EarlyView.
As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...
