Researchers have fabricated a metallic waveguide with a nano-sized cavity to select certain wavelengths of light. This work may contribute to developing devices that can compute based on light instead ...

Fig. 1. (a) Schematic diagram of synchrotron radiation by single-undulator. The temporal spread of the radiation pulse is determined by the spatial distribution of electron bunch. (b) The radiation ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

A new concept for energy transfer between gravitational waves and light. When massive cosmic objects such as black holes merge or neutron stars crash into one another, they can produce gravitational ...

Researchers at the University of Tsukuba use tiny nanocavities embedded in waveguides to selectively modify short light pulses, which may help lead to ultrafast optical pulse shaping for use in new ...
