This setup enabled flexible control of the optical ... fiber laser. At the frequency corresponding to the least common multiple of the harmonic orders, the equivalent Δf rep of the harmonic dual ...

As a postdoc Diddams built the first optical frequency combs in the lab of Nobel laureate John Hall ... National Laboratory where he modeled a hollow-core photonic crystal fiber based carbon-dioxide ...

The Fiber Sources and Applications Group at NIST has a long-standing focus on the application of optical frequency combs to time-frequency transfer and ranging. This focus places us at an intersection ...

As light enters the fiber at a specific angular position ... According to this principle, a periodic train of optical pulses ...

Andrew Weiner and co-workers from the USA now demonstrate a reconfigurable and tunable flat-top microwave photonic filter using an electro-optic frequency comb and a dispersive medium, in which ...

“Mechanical frequency combs are poised to bring the applications and utility of optical frequency combs into the mechanical domain. So far, their main challenge has been strict requirements on drive ...

These specialized optical fibers incorporate a microstructured arrangement of material in their cross-section, typically in the form of air holes running along the fiber's length. This unique ...
