Abstract:

We present silicon nitride photonics on glass (SING), demonstrated at the wafer-level, establishing its feasibility for high-density optical redistribution layers (RDLs) in panel-level packaging. Demonstrated passive components support 106 Gbps transmission, enabling scalable wafer-level optical interconnects with grating couplers, ring resonators, MMI couplers, MZIs, and stitched waveguides. With a compact 100 µm bend radius, SING enables a 10× higher density than LDW or IOX glass platforms, while remaining compatible with large-panel processing. This positions SING as a promising and scalable solution for next-generation optical RDLs.

Determination of Crystal Structures

In the late 1800s, the revelation that light extended beyond visible wavelengths led to the discovery of X-rays by Wilhelm Roentgen. Recognized as high-energy electromagnetic radiation with short wavelengths, X-rays prompted exploration into their interaction with crystals. Max von Laue proposed in 1912 that the periodic arrangement of atoms, ions, or molecules in crystals would cause them to diffract X-rays, a hypothesis confirmed through experiments with copper sulfate and zinc sulfide...
