Defying conventional wisdom, researchers have uncovered a novel coupling mechanism involving leaky mode, previously has been considered unsuitable for high-density integration in photonic circuits.

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 ...

(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 ...

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 ...

There are different antenna options for transmitting and receiving a radar signal. This blog will focus on how to connect a monolithic microwave integrated circuit (MMIC) radar transceiver to the ...

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 ...

Researchers have succeeded in making the thinnest ever optical device in the form of a waveguide just three atomic layers thick. The device could lead to the development of higher density ...

A novel differentiable approach optimizes geometric waveguide coatings, achieving substantial gains in light efficiency and ...

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 ...
