Abstract

The invention discloses a retrieval structure of an optical packet head used in an exchange network of an asynchronous optical packet, which comprises a light splitter, a reflective semiconductor amplifier, a first circulator, a second circulator and a coupler; an input terminal of the light splitter is connected with packet input waveguide; a first output terminal of the light splitter is connected with a d port of the second circular through fiber delay lines, so that control signals which pass through the light splitter and are delayed are inputted to the reflective semiconductor amplifier; a second output terminal of the light splitter is connected with an a port of the first circulator; a b port of the first circulator is connected with the input/output terminal of the reflective semiconductor amplifier; a c port of the first circulator is connected with a first input terminal of the coupler; the input/output terminal of the reflective semiconductor amplifier is connected with an e port of the second circulator; an f port of the second circulator is connected with a second input terminal of the coupler. The retrieval structure of the optical packet head can increase on-off ratio of a system.

Description

technical field [0001] The invention relates to an all-optical packet header extraction structure based on a reflective semiconductor optical amplifier (RSOA), in particular to an optical packet header extraction structure used in an asynchronous optical packet switching network. The invention can be used in high-speed optical transmission links to realize the extraction of the optical packet header (that is, the address code) in the optical packet. technical background [0002] The optical packet switching technology (The optical packet switching OPS) is considered to be the most promising switching technology in the third generation optical network. Due to the lack of optical RAM technology, all-optical routing has become an important bottleneck in the development of optical networks. But on the other hand, all-optical routers can be developed to realize switching and competition mechanisms in the wavelength domain, and at the same time can realize high-speed multi-wavele...
