Optics normally treats the behaviour of packages of light waves (photons). However, when passing through appropriately shaped fields, particles may behave similar as photons. A beam of electrons that…

Future technology such as quantum cryptography and computation, or perhaps even larger scale teleportation, requires a deeper understanding of the phenomenon known as "entanglement", the quantum non-…

When light is used to transmit information,  modulated light pulses travel along optical fibers, which can become weaker due to optical attenuation in the fiber and so are refreshed in signal…

Light beams travel in straight lines and don't go around corners, they instead spread through a process known as diffraction. Researchers at Tel Aviv University have discovered that small beams of…

What is nonlinear optics?Nonlinear optics is a branch of optics which studies the nonlinear interactions of electromagnetic radiation and the media. The nonlinear interaction, which means the matter…

Lasers can now generate light pulses down to 100 attoseconds thereby enabling real-time measurements on ultrashort time scales that are inaccessible by any other methods. Scientists at the Max Born…

Please note-I am not in to crystals, essential oils or new age

Caltech researchers have created a nanoscale crystal device that allows them to confine both light and sound vibrations in the same tiny space. The interactions between sound and light in this…

A marine crustacean could inspire the next generation of DVD and CD players, says a new study in Nature Photonics. Mantis shrimps found on the Great Barrier Reef in Australia have the most complex…

The power of quantum mechanics for data transmission is intriguing because of potential for secure, high speed communications but current storage and transmission of quantum information is far too…
