Latest Frequency comb Stories
Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength.
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.
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.
By combining advanced laser technologies in a new way, physicists at the National Institute of Standards and Technology (NIST) have generated microwave signals that are more pure and stable than those from conventional electronic sources.
Purity of ingredients is a constant concern for the semiconductor industry, because a mere trace of contaminants can damage or ruin tiny devices.
World first: PTB researchers transfer ultra-stable frequency across a 480 km long optical fiber link- Comparison of optical clocks is becoming much simpler.
Physicists at the University of Maryland have found a way to turn a precision measurement device into a versatile tool for manipulating quantum bits (qubits).
Finally, an optical frequency comb that visibly lives up to its name.
The National Physical Laboratory (NPL) has helped to establish that femtosecond comb lasers can provide accurate measurement of absolute distance in formation flying space missions.
Researchers at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass have created an "astro-comb" to help astronomers detect lighter planets, more like Earth, around distant stars.
