Embodiment Construction

[0033] The present invention will be further described below in conjunction with embodiment, but should not limit protection scope of the present invention with this.

[0034] see first Figure 4 , Figure 4 : Structural schematic diagram of Embodiment 1 of the tunable dispersion compensator of the present invention, as can be seen from the figure, the composition of the tunable dispersion compensator of the present invention includes:

[0035] A G-T interferometer 1, the G-T interferometer 1 is composed of a highly reflective flat mirror 11 and a partially reflective flat mirror 12 parallel to each other;

[0036] A high reflection plane mirror 2 is extended on the plane where the two parallel plane mirrors of the G-T interferometer 1 are located;

[0037] Partial reflection flat mirror 12 side of this G-T interferometer 1 is provided with a double-fiber collimator assembly 3, and this double-fiber collimator assembly 3 is formed in series by the pigtail optical fiber of it...

Abstract

An adjustable dispersion compensator characterizes in including a G-T interferometer made up of a parallel high reflection plane mirror and a partial reflection plane mirror, a high reflection plane mirror is extended at the plane of the two parallel planed mirrors, a pair of fiber collimators set at the side of the partial reflection plane mirror and formed by orderly serial tail fibers, among which, all double fiber collimators are vertical to said partial reflection plane mirror. The compensator also includes one diameter mobile platform fixing said G-T interferometer and an adjusting unit controlling operation of the platform.

Description

technical field [0001] The invention relates to an optical fiber communication system, in particular to an adjustable dispersion compensator based on a combined Gires-Tournois interferometer. The device is mainly used in optical fiber communication systems, which can compress the optical pulse width and restore the signal waveform. Background technique [0002] With the rapid development of optical communication systems, especially the development of high-speed, multi-channel dense wavelength division multiplexing optical fiber communication systems, multi-channel optical fiber dispersion compensation technology has become one of the key technologies. Various multi-channel dispersion compensation technologies have been developed in recent years, which can be roughly divided into two categories: dispersion compensation fibers and dispersion compensation devices, each of which has its own advantages and disadvantages. Among dispersion compensating devices, fiber gratings and ...
