Embodiment Construction

[0045]Embodiment 1 of the present invention provides an optical fiber amplifier and a manufacturing method thereof, using integrated optical devices based on Free Space (free space) integration technology to form a compact optical fiber amplifier. The FreeSpace integration technology refers to assembling and integrating various optical functional elements on a two-dimensional or three-dimensional optical platform, and controlling the propagation direction of the beam in free space through the principle of reflection, transmission or refraction. The beam in free space passes through Various optical components are used to realize the processing of various optical functions required. The beam propagation direction is not limited to one dimension in space, and the light does not need to be confined in the dielectric waveguide during the propagation process.

[0046] The Free Space integrated optical device described in the embodiments of the present invention refers to the integrat...

Abstract

The invention relates to an optical fiber amplifier and a production method thereof, as well as an optical fiber communication system, which pertain to the field of optical fiber communication technology. The optical fiber amplifier comprises at least one pump laser, at least one section of gain medium and at least one integrated optical device; wherein the integrated optical device comprises a plurality of light input ports and light output ports, which are directly or indirectly connected with the pump laser or the gain medium. The invention solves the problems of a prior optical fiber amplifier such as a large number of discrete devices and combined devices, and instability in performances and difficulty in compression of the volume due to the large quantity of optical fiber fusion splices. At the same time, the invention reduces the complexity and the cost of the production, and improves the production efficiency of the optical fiber amplifier.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical fiber amplifier, a manufacturing method and an optical fiber communication system. Background technique [0002] Optical fiber communication systems are divided into single-wave optical fiber communication systems and wavelength division multiplexing optical fiber communication systems according to the number of optical signals carrying service information. [0003] The typical structure of the single-wave optical fiber communication system is as follows: figure 1 As shown, the transmitter TX emits signal light with a wavelength of λ, and then the signal light is input into the optical fiber amplifier at the sending end, the power of the signal light is amplified and increased, and the signal light is amplified and propagates in the transmission fiber. Since the transmission fiber has loss characteristics, in The signal light propagating in the tra...
