Embodiment Construction

[0021] In order to solve the problem in the prior art that it is very difficult to weld the double-clad optical fiber and the photonic crystal optical fiber, the invention provides a connection method for the double-clad optical fiber and the photonic crystal optical fiber.

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as image 3 as shown, image 3 It is a flow chart of a method for connecting a double-clad fiber and a photonic crystal fiber according to an embodiment of the present invention.

[0024] Step S310, tapering the double-clad optical fiber.

[0025] Tapering is a fiber processing technology, that is, the fiber is heated and thinned, and the diameter of the fiber core and cladding can be changed by tapering. ...

Abstract

The invention discloses a double-clad fiber and photonic crystal fiber connecting method. The method includes the steps that a double-clad fiber is tapered, and the tapered double-clad fiber and a photonic crystal fiber are connected through a transition fiber. The method effectively solves the problem that the double-clad fiber and the photonic crystal fiber are difficult to connected in a melting mode in the prior art. The double-clad fiber and the photonic crystal fiber are connected through the transition fiber, so that the double-clad fiber and the photonic crystal fiber are prevented from being connected directly. Besides, before connection, the double-clad fiber is tapered, so that the fiber core diameter and the cladding diameter of the double-clad fiber are reduced. By means of the method, connection difficulty of the double-clad fiber and the photonic crystal fiber can be effectively lowered.

Description

technical field [0001] The invention relates to the technical field of laser electronics, in particular to a connection method between a double-clad optical fiber and a photonic crystal optical fiber. Background technique [0002] Photonic Crystal Fiber (PCF) is a microstructured fiber composed of a single medium. The photonic crystal fiber is composed of air holes on the order of wavelength that are closely arranged in the two-dimensional direction and basically keep the same in the third dimension (the axial direction of the fiber). Among them, the core layer of the photonic crystal fiber with the total reflection structure is a solid core material, and the cladding layer is a periodic air hole structure. [0003] Photonic crystal fiber has the characteristics of adjustable dispersion and high nonlinearity, which can be used as a nonlinear spectrum stretcher in broadband fiber lasers to play the role of spectrum broadening. The working diagram of the broadband fiber lase...
