Embodiment Construction

[0015] The present invention is a new type of pulse spectrum stretcher, specifically relates to the use of highly nonlinear fiber (HNLF) with high normal dispersion value to form a 40GHz optical pulse sequence spectrum stretcher to provide high pulse as wavelength division multiplexing (WDM) Repetition frequency broadband coherent light source. For the 40GHz pulse sequence with limited peak power amplification, the new pulse spectrum stretcher adopts the chirped pulse compression technology, and realizes the pulse spectrum broadening by improving the generation efficiency of the supercontinuum (SC) of the HNLF. Improved significantly.

[0016]The construction principle of the pulse spectrum stretcher of the present invention is as follows: firstly, according to the characteristics of the input pulse and the highly nonlinear fiber (HNLF) used, the lengths of the standard single-mode fiber (SMF) and the two sections of HNLF are determined. The length of the HNLF is determined a...

Abstract

The present invention is an optical pulse sequence spectrum stretcher based on highly nonlinear optical fibers, which is provided with highly nonlinear optical fibers (1) and (3) of different lengths, and a standard single-mode optical fiber (2) is fused between them; It is used as a wavelength division multiplexed 40GHz high pulse repetition frequency broadband coherent light source. For a pulse sequence with a high pulse repetition frequency such as 40GHz, when the peak power amplification of the pulse is limited, the spectrum stretcher of the present invention adopts the chirped pulse compression technology, and realizes the further effective broadening of the pulse spectrum by improving the spectral broadening efficiency of HNLF, that is With the same pump pulse input and using the same length of HNLF, the pulse spectral broadening will be significantly improved.

Description

technical field [0001] The invention relates to a device in optical fiber communication, especially a 40GHz optical pulse sequence spectrum stretcher based on a highly nonlinear optical fiber to provide a broadband coherent light source with a high pulse repetition frequency for wavelength division multiplexing (WDM). Background technique [0002] With the rapid development and wide application of the Internet (INTERNET) and IP technology, various new bandwidth services are emerging, and the demand for information in the society is increasing exponentially. Due to the huge bandwidth potential of the optical fiber communication system, it occupies an important position in the communication system. proportion will increase. The all-optical network based on dense wavelength division multiplexing (DWDM) technology has been recognized as an effective way to alleviate the growing communication capacity problem. The common way to improve communication capacity by using WDM technolo...
