While those Verizon and AT&T commercials may claim that the respective carrier has the “fastest” network for mobile phones, new communications technology could make today’s 3G and 4G networks look as antiquated as the telegram.

Scientists Confirm First 'Frequency Comb' To Probe Ultraviolet Wavelengths

Existing coherent ultraviolet light sources are power hungry, bulky and expensive. Researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve information storage, microscopy and chemical analysis.

NIST's Compact Frequency Comb Could Go Places
2011-10-27 04:51:47

Laser frequency combs—extraordinarily precise tools for measuring frequencies (or colors) of light—have helped propel advances in timekeeping, trace gas detection and related physics research to new heights in the past decade.

2011-10-20 09:27:39

Researchers at Purdue University and the National Institute of Standards and Technology (NIST) have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ultrashort pulses, a technology that might have applications in more advanced sensors, communications systems and laboratory instruments.
