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 ...

The physical interaction between two or more systems, also known as coupling, can give rise to unique and unexpected effects.

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

In an experiment packed with scientific firsts, researchers have demonstrated that a laser pulse can accelerate an electron beam and couple it to a second laser plasma accelerator, where another laser ...

Integrated photonics extensively uses on-chip optical elements such as sources, splitters, modulators, and high-confinement waveguides embedded in a planar platform to efficiently process and route ...

Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

Silicon (Si) photonics has recently emerged as a key enabling technology in many application fields thanks to the mature Si process technology, the large silicon wafer size, and Si optical properties.

(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 ...
