A sharp-edged aperture is a promising solution for eliminating side lobes from superoscillatory waves. Optical superoscillation refers to a wave packet that can oscillate locally in a frequency ...

Sir Chandrasekhara Venkata Raman and his student Nagendra Nath published a series of papers in 1936 on the diffraction of light by a liquid in the field of a high frequency sound wave. This was ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

Australian researchers design an optical fiber that focuses light in the far field without using lenses. Researchers in Australia have designed an air-silica optical fiber that overcomes free-space ...

In recent years, the rapid growth of artificial intelligence and the Internet of Things (IoT) has driven a surge in computational demand. Traditional electronic computing, however, is approaching its ...

With the development of photonic chips and nano-optics, the old ground glass lenses can't keep up in the race toward miniaturization. In the search for a suitable replacement, a team from the ...

Optical superoscillation refers to a wave packet that can oscillate locally in a frequency exceeding its highest Fourier component. This intriguing phenomenon enables production of extremely localized ...
