(PhysOrg.com) -- Silicon is an ideal platform for integrated photonic circuits because the material is cheap and readily available. Silicon chips with an integrated laser source capable of emitting ...

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 ...

Diffraction gratings are periodic optical structures that disperse incident light into constituent wavelengths by interference. They form a cornerstone of modern optical instrumentation, underpinning ...

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 ...

This paper describes the invention of distributed feedback (DFB) structures for integrated optics. The realization of complex structures was carried out in acoustics as cascades of Surface Acoustic ...

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 ...

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 ...

I often wonder if there is something beyond our grasp and perhaps “other-worldly” about elemental Silicon (Si), which is the primary material for most ICs and discrete semiconductors work. Yes, there ...

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 ...
