Abstract

The present invention provides a soliton optical frequency comb generation device and an operation method thereof. The device comprises an adjustable pulse laser, a first connection optical fiber, anoptical amplifier, a second connection optical fiber, a polarization controller, a third connection optical fiber, a first circulator, an assistant test output optical fiber, a fourth connection optical fiber, a ceramic ferrule microcavity, single-layer grapheme, an output optical fiber, a first C-type ceramic tube and a second C-type ceramic tube. The device employs the single-layer grapheme andthe FP microcavity structure to generate a soliton optical frequency comb with 10GHz frequency comb intervals in a condition without tuning of the pump laser frequency, and therefore, the soliton optical frequency comb generation device and the operation method thereof are high in integration level, low in power consumption, simple and convenient to operate and good in output result repeatability.

Description

technical field [0001] The invention relates to an optical frequency comb, in particular to an optical frequency comb generating device and an operation method. Background technique [0002] An optical frequency comb (referred to as an optical frequency comb) is a laser light source that has a series of equally spaced and discretely distributed frequency components on the spectrum. Due to the precise frequency interval, definite phase relationship and wide spectrum range between the comb lines of the optical frequency comb, it has important application requirements in atomic clocks, trace gas detection, optical waveform synthesis, dense wavelength division multiplexing and other systems. [0003] The early optical frequency comb generation scheme was based on laser mode-locking technology, but it was limited by problems such as high system power consumption, large volume, and low repetition rate, and its application scenarios were limited to laboratories. In the past decade...

Problems solved by technology

The experimental results of this scheme depend on the frequency sweep speed and modulation depth of the modulation signal, and the experimental results will also be affected by the thermo-optic effect

[0009] In short, the above methods are either limited by the thermo-optic effect or by the sweeping speed of the extracavity pump laser, the repeatability of the experimental results of generating soliton optical frequency combs is poor, and it is impossible to automatically generate a single frequency comb through program control.
