By placing single-atom-thick adlayers of p-block metals on commonly employed gold electrodes (d-block), a research team at National Taiwan University has successfully quantified the "interfacial ...

Researchers have built a microscopic 3D-printed optical device that funnels light from 37 separate multimode semiconductor lasers into a single optical fiber, merging 222 distinct spatial modes; the ...

Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a single multimode optical fiber with very low loss ...

Scientists from Germany, Japan, and India have demonstrated that femtosecond laser pulses can force an entire layer of molecules to rotate in unison on a two-dimensional quantum material, a result ...

Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a ...

Abstract: In this letter, a compact and broadband directional coupler is proposed for high-power radio frequency applications in the frequency band of 5-150 MHz. The coupler is composed of a suspended ...

Abstract: In this work, we demonstrate an edge coupler (EC) for the coupling between the single mode fiber (SMF) and the silicon photonic waveguide. High coupling efficiency can be achieved by using ...
