Abstract

An all-fiber short-wave infrared electro-optic frequency combs (SWIR E-O combs) based on parametric amplification is proposed and experimentally demonstrated by converting the near-infrared combs into the shortwave infrared region. The SWIR E-O combs shows tunable central wavelength and spectral line spacing. Based on the simple combination of the fiber optical parametric amplifier and the Thulium-doped fiber amplifier directly pumped by C-band E-O combs, the power of SWIR E-O combs has been effectively enhanced. In addition, a section of single-mode fiber is used for pulse compression of the C-band E-O combs, and the 10 dB spectral width of the SWIR E-O combs is 17.81nm. The proposed SWIR combs with repetition rates of tens of GHz is of high interest for coherent communication and gas sensing in the SWIR region.

基于宽带参数转换的短波红外电光频率梳的生成

提出了一种基于参数放大的全光纤短波红外电光频率梳（SWIR E-O梳），并通过将近红外梳转换为短波红外区进行了实验验证。SWIR E-O梳显示出可调谐的中心波长和谱线间距。通过光纤参量放大器与c波段E-O梳直接泵浦掺铥光纤放大器的简单组合，有效地提高了SWIR E-O梳的功率。此外，采用一段单模光纤对c波段E-O梳进行脉冲压缩，得到SWIR E-O梳的10 dB谱宽为17.81nm。所提出的重复频率为数十GHz的SWIR梳对SWIR区域的相干通信和气体传感具有很高的兴趣。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
