Embodiment Construction

[0020] Further detailed description will be given below in conjunction with the accompanying drawings and embodiments.

[0021] The steps of preparing optical fiber microstructure device in this embodiment are as follows:

[0022] a) Cut a piece of ordinary single-mode fiber 1-3, with a core of 9 μm and a cladding of 125 μm. After peeling off a 6 mm long section of the coating layer at one end of the fiber 1-3 with pliers, apply a layer of optical fiber glue on the bare fiber, and insert Among the capillary tubes 1-5 with a bell mouth 3-1 at one end, the capillary tube 1-5 is 9 mm long, with an inner diameter of 0.126 mm and an outer diameter of 1.8 mm. The horn mouth 3-1 clamps the coating at the other end of the optical fiber 1-3, Fill the bell mouth 3-1 with glue to fix the optical fiber 1-3 to form an optical fiber-capillary structure 2-5 with an optical fiber pigtail at one end. Grind to smooth on the same plane of 90 degrees radial direction of optical fiber 1-3;

Abstract

The invention discloses a colloidal crystal-modified optical fiber-capillary microstructural device, which is manufactured by the following main steps of: removing a coating from the common standard monomode optical fiber, inserting the optical fiber into a capillary, fixing the optical fiber by using glue, and polishing a capillary-optical fiber end face; preparing colloidal microsphere solutionfrom different materials such as polystyrene (PS), polymethyl methacrylate (PMMA) and silica; growing a colloidal crystal on the capillary-optical fiber end face by a vertical deposition method, sintering by using a sintering furnace and curing to form a colloidal crystal capillary-optical fiber microstructure; and packaging and fixing by using a thermoplastic sleeve and a plastic box. The formedcolloidal crystal-modified capillary-optical fiber microstructure can have a porous structure and can be manufactured into an optical fiber filter and a biological environmental sensor through further development; and the common optical fiber is utilized, so the device is easy and convenient to manufacture and low in cost.

Description

technical field [0001] The invention relates to a microstructure device, in particular to an optical fiber microstructure device and a preparation method thereof. Background technique [0002] Applying the bandgap structure of photonic crystals to optical fibers forms photonic crystal fibers (Photonic Crystal Fiber, PCF), also known as microstructured optical fibers. Using UV write-out technology or CO 2 Thermal shock technology can write photonic crystal fiber gratings in PCF. Microstructured fiber gratings have rich structural and optical properties. Changing the microhole arrangement, size and duty cycle in the fiber, or loading the medium into the microhole can change the optical properties of the photonic crystal fiber and its grating, and greatly change the performance of the fiber microstructure. However, its production cost is high, and there are many problems in its connection with ordinary optical fibers. [0003] To manufacture photonic crystals in the opti...
