WebDec 2, 2024 · Figure 1 shows a schematic diagram of the Er:fiber femtosecond frequency comb stabilized to the optical standard. Radiation of the femtosecond erbium-doped fiber laser after passage through the AOFM is divided into two parts. Then it is amplified and broadened by highly nonlinear fibers [ 24, 25 ]. Reset image size Figure 1. WebOct 16, 2024 · A new scheme to generate ultra-flat optical frequency comb (OFC) with tunable frequency spacing is proposed and demonstrated based on an amplitude modulator driven by a digital periodic square-wave signal. A Gaussian band-stop filter is used to adjust flatness of the comb lines that generated from the amplitude modulator.

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. … See more In optics, a frequency comb is a laser source whose spectrum consists of a series of discrete, equally spaced frequency lines. Frequency combs can be generated by a number of mechanisms, including periodic modulation … See more For many applications, the comb must be widened to at least an octave: that is, the highest frequency in the spectrum must be at least twice the lowest frequency. One of three techniques … See more In the absence of active stabilization, the repetition rate and carrier–envelope offset frequency would be free to drift.
