    It has long been known that the optical resonances of ultrahigh-Q whispering gallery mode resonators can split under the influence of particle scattering. Now scientists have exploited this splitting to accurately determine particle sizes.

    Could 2010 be the year that 3D display technology takes off in cinemas and homes? All the signs suggest that the answer is yes.

  • Industry Perspective |

    Extreme ultraviolet lithography extends photolithography to much shorter wavelengths and is a cost-effective method of producing more-advanced integrated circuits. Although some infrastructure challenges still remain, this technology is expected to begin high-volume microchip production within the next three years.

    The entanglement of squeezed light beams is critical for quantum optical applications, but has so far been achieved with only two light beams. Now, researchers have surpassed this restriction and achieved entanglement with three beams of different colours. They also report a finite loss level for disentanglement of one beam from the other two.
