Future electronics may depend on lasers, not quartz

Nearly all electronics require devices called oscillators that create precise frequencies - frequencies used to keep time in wristwatches or to transmit reliable signals to radios. For nearly a century, these oscillators have relied upon quartz crystals to provide a frequency reference, much like a tuning fork is used as a reference to tune a piano. A new approach could ultimately replace the quartz crystal frequency reference - technology in use since the 1920s.

'Nanocamera' takes pictures at distances smaller than light's own wavelength

Researchers have demonstrated that an array of novel gold, pillar-bowtie nanoantennas can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light. A standard optical microscope acts as a 'nanocamera' whereas the pillar-bowtie nanoantennas are the analogous film.

Plasmon-enhanced polarization-selective filter

This structure composed of multiple holes array by filling it with nonlinear medium combines the characteristics of selectable wavelength, enhanced transmission, polarization separation and output control by the intensity of incident light. This result is useful for integrated optical circuits and on-chip optical interconnects.

Extreme nanostructures value proposition

Super-critical fluid electro-deposition (SCFED) integrates well proven technologies to offer a disruptive, scalable approach to building metal and semiconductor nanostructures an order of magnitude smaller than is achievable using photolithography.

Fundamental chemistry findings could help extend Moore's Law

In a bid to continue decreasing transistor size while increasing computation and energy efficiency, chip-maker Intel has partnered with researchers from Lawrence Berkeley National Lab to design an entirely new kind of resist. Results could be easily incorporated by companies that make resist, and find their way into manufacturing lines as early as 2017.
