A frequency comb allows a direct link from radio frequency standards to optical frequencies. Current frequency standards such as atomic clocks operate in the microwave region of the spectrum, and the frequency comb brings the accuracy of such clocks into the optical part of the electromagnetic spectrum.
31 de dic. de 2009 · Optical frequency combs are specialized lasers that act like a ruler for light. They measure exact frequencies of light — from the invisible infrared and ultraviolet to visible red, yellow, green and blue light — quickly and accurately. These Nobel Prize-winning devices fill an important technological gap.
6 de dic. de 2019 · The optical frequency comb (OFC) was originally developed to count the cycles from optical atomic clocks. Atoms make ideal frequency references because they are identical, and hence...

A frequency comb can be used as an optical ruler: If the comb frequencies are known, the frequency comb can be used e.g. to measure unknown frequencies by measuring beat notes, which reveal the difference in frequency between the unknown frequency and the comb frequencies.
Un peine de frecuencias o peine espectral es un espectro formado por líneas espectrales discretas y regularmente espaciadas. En óptica, algunas fuentes láser pueden generar un peine de frecuencias.
1 de jun. de 2016 · The optical frequency comb technology is one of the most important breakthrough in photonics in recent years. This concept has revolutionized the science of ultra-stable lightwave and microwave signal generation.
21 de feb. de 2019 · A frequency comb is a spectrum of phase-coherent evenly spaced narrow laser lines (Fig. 1a ). Frequency combs 1 revolutionized time and frequency metrology in the late 1990s...
