The integration of beam splitters and grating structures is central to contemporary developments in optical engineering. These devices, which manipulate light via diffraction and interference, are ...

Optical microelectromechanical systems (MEMS) devices are driving the trend toward all-optical telecommunication networks. With the ability to directly manipulate an optical signal, MEMS have several ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

1.The concept and principle of optical reticle. The optical reticle, also known as an optical grating or grating plate, is an optical element with a periodic structure, usually made of a transparent ...

As the demand for bandwidth and high-speed transport grows, so does the use of fiber-optic based transport. One of the enabling technologies associated with optical transport are Fiber Bragg gratings ...

Fiber Bragg Grating technology bests conventional dispersion compensation fiber in terms of attenuation and bandwidth in the new 40- and 100-Gbit/s optical networks. The pursuit of faster and more ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...
