The light is composed of a range of frequencies separated very precisely by the same distance, producing what physicists call a frequency comb, since it resembles the regular spacing between the teeth of a comb.

The cavity will have multiple cavity resonant modes, or a comb of frequencies spaced apart, as determined by the parameters of the cavity, including the length of the cavity.

In accordance with the invention, the offset frequency of the spectral lines of the optical frequency comb is adjustable by time‑proportional phase setting by means of the phase setter (5).

Methods and systems are disclosed for simultaneous line narrowing of cw lasers, as well as referencing the desired emission wavelength to a frequency comb laser.

The regularly spaced bright spots just above the lines are the spectrum of the laser frequency comb that is used for comparison.

His current research of field is the study of dynamics of semiconductor lasers subject to a frequency comb optical injection.

Petek and his team were able to observe the production of such a comb of frequencies from a crystalline solid for the first time.

The section includes a non-linear optical element generating a frequency converted spectral output having a spectral bandwidth and a frequency comb comprising harmonics of the oscillator repetition rates.

An optical frequency comb generator for generating from first and second signal sources a plurality of signals with fixed frequency spacing derived from the second signal source frequency.

A multiple wavelength light source (400) generates an output signal having a comb of accurately spaced apart frequencies with variable free spectral range in the C-band of optical fiber communication.

Feedback loops can be used to shift and stabilize the carrier-envelope phase of a frequency comb from a mode-locked fibers laser or other optical source.
