Embodiment

[0033] Such as figure 1 Shown, a kind of cladding filter fabrication method based on laser reduction graphene oxide microstructure comprises the following steps:

[0034] made as figure 1 Side polished fiber shown;

[0035] Such as figure 2 As shown, make a tank-type device for depositing graphene oxide on the side-polished optical fiber, and use this device to package the side-polished optical fiber;

[0036] Depositing graphene oxide on the side-polished optical fiber includes: ultrasonically treating the graphene oxide solution so that the graphene oxide is evenly distributed in the aqueous solution to avoid clustering of graphene oxide; depositing on the side-polished optical fiber Graphene oxide film, that is, take out the graphene oxide solution and drop it into the groove of the sink-type device, and place it for a period of time to allow the water to evaporate, so that the polishing surface of the side-polished optical fiber is completely covered by the graphene ox...

Abstract

The invention discloses a cladding filter based on laser-reduced graphene oxide microstructure and its manufacturing method, which uses purple light irradiation to reduce graphene oxide, and deposits the processed graphene oxide on the packaged side-polished optical fiber Afterwards, the polished surface can be observed through an optical microscope and a scanning electron microscope to verify that graphene oxide has covered the polished surface. Finally, use an amplitude mask to write on the graphene oxide on the polished surface The grating structure forms a cladding refractive index modulated optical fiber grating, thereby preparing a cladding refractive index modulated optical fiber grating of graphene oxide-graphene periodic structure.

Description

technical field [0001] The invention relates to the field of filters, in particular to a method for manufacturing a cladding filter based on laser reduction graphene oxide microstructure. Background technique [0002] Graphene oxide is used as a precursor for the preparation of graphene, and graphene sheets with high yield and low cost can be obtained by reducing graphene oxide. In addition, the presence of carboxyl, hydroxyl and other polar groups on the surface of graphene oxide is conducive to the preparation of graphene derivatives, which will expand the application field of graphene. Commonly used reduction methods mainly include: using reducing agent, thermal reduction, and light-induced reduction. The light-induced reduction method proposed in recent years is based on the principle of photothermal reduction. This method has the characteristics of high speed, environmental protection and flexibility. With the widespread attention and development of graphene oxide in ...
