I WISH to direct attention to a very remarkable property possessed by one of the systems of interference bands which make their appearance when white light is reflected from a plane replica-film ...

Transient grating spectroscopy is an elegant method that uses two laser pulses to activate a medium by creating an interference pattern made of parallel stripes of excitations that can be thermal, ...

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 ...

At the quantum boundary This experiment at the University of Vienna proves that objects as big as molecules can interfere. (Image: Robin Riegler) Ever since quantum theory was developed during the ...

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 ...
