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.
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.
