This means they could support further integration of electronics and optics and could be mass produced—a path toward commercially viable, compact optical clocks. NIST’s chip-based optical clock has an ...

Chip-scale optical clocks like this could eventually replace traditional oscillators in applications such as navigation systems and telecommunications networks and serve as backup clocks on ...

A new generation of small-scale optical clocks could better coordinate the flow of data through telecommunication networks, or sync up far-flung telescopes to make astronomical observations (SN: 4 ...

The chip-scale clock is based on the vibrations, ... NIST’s chip-based optical clock has an instability of 1.7 x 10 −13 at 4,000 sec., ...

Chip scale atomic clocks are being developed by DARPA. The goal of the Chip-Scale Atomic Clock program is to create ultra-miniaturized, low-power, atomic time and frequency reference units that will ...

“Shrinking atomic clocks from large cesium beam tubes to chip-scale devices without eroding performance requires a rethinking of a number of critical components, including vacuum pumps and optical ...

The chip-scale clock is less accurate than larger atomic clocks such as fountain clocks. However, the clock’s small size, low power dissipation and potentially low cost make it ideal for a ...

“This is the first demonstration of a magnetic-free, electrically driven linear optical isolator on-a-chip, using Complementary Metal-Oxide Semiconductor (CMOS)-compatible fabrication technology and ...

The Chip Scale Atomic Clock is a matchbox-sized atomic clock, that uses one one-hundredth the power of its conventional counterparts (Photo: Symmetricom Inc.) View gallery - 3 images ...

The chip-based heart of the new clock requires very little power (just 275 mW) and, with additional technology advances, could potentially be made small enough to be handheld. Chip-scale optical ...

An experimental, next-generation atomic clock -ticking at high "optical" frequencies -that is much smaller than usual, made of just three small chips plus supporting electronics and optics, has been ...
