on electrons moving through
silicon - based
chips — which, despite huge advances, are still less efficient than photonics.
Their findings elucidate the physics of
light - matter coupling at these scales — and pave the way for enhanced signal processing

To help do that, the U engineers created a much smaller form of a polarization beamsplitter (which looks somewhat like a barcode)
on top of a
silicon chip that can split guided incoming
light into its two components.

A team of researchers has built an array of
light detectors sensitive enough to register the arrival of individual
light particles, or photons, and mounted them
on a
silicon optical
chip.
As the group reports in Applied Physics Letters, from AIP Publishing, integrating subwavelength cavities — the essential building blocks of their tiny lasers — onto
silicon enabled them to create and demonstrate high - density

chip light - emitting elements.
To improve the efficiency of waveguides — devices that guide
light on the surface of
silicon optical computer
chips — a complex balance must be struck.
