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 ...

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 ...

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 ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...
