Abstract: We report on two edge-coupling and power splitting devices for hybrid integration of III-V lasers with sub-micrometric silicon-on-insulator waveguides. The proposed devices relax the ...

In shipbuilding and marine maintenance, precision alignment is not a detail—it is a prerequisite for reliability, efficiency, and long service life. From propeller shafts and gearboxes to diesel ...

Abstract: Laser integration, optical coupling, and assembly are challenging problems that need to be further addressed to reduce the manufacturing costs of silicon photonic-based products. In this ...

In the mesosphere, vertical wind velocities can exceed tens of m/s, driven by gravity wave (GW) processes such as wave breaking and the generation of secondary GWs. These dynamic events play a crucial ...

Moving photonic ICs into the same package as silicon helps improve performance, but lasers remain outside. A new monolithic laser array allows hundreds of colors, each individually software-tunable ...

Scientists have developed a groundbreaking technique called RAVEN that can capture the full complexity of an ultra-intense laser pulse in a single shot—something previously thought nearly impossible.

This important paper presents a thoroughly detailed methodology for mesoscale-imaging of extensive areas of the cortex, either from a top or lateral perspective, in behaving mice. The examples of ...

This study aims to examine the role of neurovascular coupling (NVC) in vascular cognitive impairment (VCI) by investigating the relationship between white matter lesion (WML) burden, NVC, and ...

Two-dimensional infrared absorption (2D-IR) spectroscopy is severely limited in its application to larger proteins due to broad and overlapping signals in the amide I region. Here, we overcome this ...
