Recently, researchers have been investigating novel approaches of beam splitting in the context of topological photonics1, a burgeoning field that explores the topological properties of photonic ...

We describe a method to detect twin-beam multiphoton entanglement based on a beam splitter and weak nonlinearities. For the twin-beam four-photon entanglement, we explore a symmetry detector. It works ...

A graphene-based “beam splitter” for electronic currents has been built by researchers in France, South Korea, and Japan. Created by Preden Roulleau at the University of Paris and colleagues, the ...

We propose a polarization beam splitter (PBS) with a footprint of only 600 × 790 nm 2 operating at a wavelength of λ = 1550 nm, which is the smallest PBS ever demonstrated. This device uses ...

These days, oscilloscope hacking is all about enabling features that the manufacturer baked into the hardware but locked out in the firmware. Those hacks are cool, of course, but back in the days of ...

Scientists have combined 3-D-printing with electroplating to easily produce high-quality metal electrodes that can be used as a molecular beam-splitter. Many measurement techniques, such as ...

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications. Bessel beams look quite different ...
