Sound engineering: The new device is a chip-based single-phonon directional coupler that carries out controllable phonon splitting. It could enable microscopic on-chip routers and splitters that link ...

A technical paper titled “Unlocking the monolithic integration scenario: optical coupling between GaSb diode lasers epitaxially grown on patterned Si substrates and passive SiN waveguides” was ...

(Nanowerk Spotlight) The concepts of metamaterials and metasurfaces have spawned massive novel applications in free-space optics. However, recent research also indicates that they possess prominent ...

What are modal effects? Integrated photonics—the devices and the materials used to make them happen. One of the key planar-waveguide configurations: the ring resonator. The roots of waveguide optics ...

Zeng, Lingzhen, Lu, Wei-Chun, Grimes, Paul K., Chen, Tse-Jun, Chang, Yen-Pin, Tong, Cheuk-yu, and Wang, Ming-Jye. 2020. "A Silicon Chip-Based Waveguide Directional ...

Most Wi-Fi and Bluetooth designs will appear to work during board bring‐up, even if the antenna feedline has a horrible mis‐match, but then you get to range testing and data integrity ...

Throughout the evolution of AR technology, display systems have consistently aimed for a balance between clarity and compactness. Diffractive waveguides, known for their slim profiles, have become ...

For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...
