Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] FIG. 4 expresses the basic principle of the present invention. The broadband light source 101 passes through a polarizer 102 and then passes through an optical filter 103 . This optical filter is not a single wavelength, but can produce a periodic filtering effect (such as a law-platinum cavity, that is, an F-P optical filter). In this way, multiple pump wavelengths will be generated after passing through the filter. Compared with common coherent lasers, these incoherent waves are already relatively broadband, and no measures need to be taken to broaden them, so they can be directly used as a pump source for the slow light system 104 . This is equivalent to having a series of pump sources at the same time. In terms of application, for multi-wavelength systems, these pump sources can act on the corresponding channels at the same time, and produce slow light eff...

Abstract

The present invention discloses a wideband light source optimizing pump arrangement for SBS slow light put-off, pump light source is provided in one or more than one channel slow light system, light path setting includes: wideband light source, first polarizer and character light device. Multiple relative stretching pump sources are outputted simultaneously with the design of the present invention by wideband light source executing periodicity filtering. The multiple pump source produced by same wideband light source can be used in multiple channel system and produces slow photo effect at the same time, and also can be used at the same time in a channel to optimizing final gain spectrum. The design of the invention reduces systemic complex degree and cost of facilities, simultaneously can dynamic optimizes systemic performance with different slow light.

Description

technical field [0001] The invention relates to the field of optical communication (including optical network) and optical information processing, especially a device for generating slow optical delay by using optical fiber. Background technique [0002] Slow optical delay uses different physical mechanisms to control the transmission speed of light in the medium for application in different fields, mainly including: (1) optical information processing; (2) optical communication systems and all-optical networks. [0003] Some key technologies in current optical communication systems and networks are still realized by converting optical signals into electrical signals, such as information storage, routing, switching and other signal processing. Obviously, the traditional photoelectric conversion can no longer meet the development needs of network capacity due to the limitation of the conversion limit rate and cost. The inevitable direction of the next generation optical commun...
