Solar material absorbs entire spectrum Design How-To 10/22/2008 Post a comment Current solar materials must be chosen to match a specific wavelength of sunlight, but a new hybrid inorganic/organic material could usher in solar cells that absorb all solar wavelengths.
Silicon ink targets RFIDs News & Analysis 10/16/2008 Post a comment Printing thin-film circuits on flexible substrates may be ready for prime time with the introduction of what is claimed as the first commercial application of silicon ink.
Researchers target diamond based lasers and apps Product News 10/13/2008 Post a comment Researchers at the Institute of Photonics, University of Strathclyde, have started work on a three and a half-year project to develop a solid-state laser design incorporating CVD (chemical vapour deposition) diamond manufactured by Element Six Ltd.
Silicon supply shifts solar dynamics Design How-To 10/6/2008 Post a comment A protracted shortage of raw silicon that impacted the fortunes for some makers of solar photovoltaic panels is beginning to ease, putting emerging thin-film panel makers under renewed pressure, said one market watcher.
CFL and LED lamps: White light in a 'green' world Teardown 10/6/2008 7 comments Despite the attention focused on alternative energies to increase available power, measures intended to conserve energy represent an equally important story. Along with "making more," the energy challenge is also to "use less."
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
