Problems solved by technology

US Patent U55637400 discloses the application of COC in optical waveguides. This patent uses COC in optical waveguide components to ensure low viscosity and low optical transmission loss. However, optical waveguides are still limited to optical fiber components.
[0007] When selecting materials for optical communication components, unsuitable materials may cause defects. For example, the materials of optical communication components are mostly made of a variety of materials, which is easy to form an incompatible interface, and this incompatible interface is likely to cause transmission signals. For example, an incompatible interface may be formed between the core part and the cladding layer of the optical waveguide made of different materials, and it is not easy to grasp the applicable materials, so it faces problems in the production of optical communication components

Embodiment 1

[0027] Firstly, the material of the COC optical communication element is prepared. The main material is divided into two parts: core section material and cladding material. The material in the core area is under the action of a unique metallocene catalyst to polymerize ethylene, bornene, and a third monomer with an active point to form a functionalized f-mCOC material. The third monomer with an active point in Example 1 The body uses 4-methyl-styrene (PMS) to form f-mCOC materials: YLC-099, YLC-087, YLC-116, YLC-105, etc., and the weight percentage (wt%) of each component is shown in Table 2. The cladding material can be self-synthesized mCOC materials, such as mCOC materials synthesized by ethylene and norbornene, or general commercial mCOC materials such as TOPAS 5013. After the material of the cladding layer is selected, the functionalized f-mCOC material in the core area can be flexibly synthesized according to actual needs, so as to jointly form the optical waveguide str...

Embodiment 2

[0043] The core area material f-mCOC can also be synthesized using photohardenable materials. In Example 2, epoxy-hexyl-bicyclo[2.2.1]heptane (epoxy-hexyl-norbornane (EHN)) and bisphenol A were used Diglycidyl ester (bisphenol A diglycidyl ether (BADE)) was used to synthesize f-mCOC materials, and core materials with different refractive indices were synthesized with different compositions.

[0044] When the cladding layer mCOC material used has a refractive index of 1.5310 (at a light wavelength of 632.8nm), it can be synthesized with the desired refractive index by adjusting different compositions, such as changing the EHN content in the f-mCOC material. The f-mCOC material in the core region of the rate value. Figure 5 Show the relationship between the refractive index of the f-mCOC material in Example 2 and the weight percentage of EHN therein; Figure 6 The relationship between the refractive index and the EHN content of the f-mCOC material in Example 2 before and after...

Abstract

An optical communication element of cycloofefin copolymer (COC) is composed of a core made of functional metallocene catalyst-COC (f-mCOC) with refractivity n1 for transmitting light and a coated layer made of metallocene-based COC (mCOC) with refractivity n2. Said n2 is less than n1. Its advantages are less transmission loss of signal and excellent optical properties.

Description

technical field [0001] The invention relates to an optical communication component, in particular to a full-polymer optical communication component composed of cycloolefin copolymer. Background technique [0002] With the continuous vigorous development of the optical communication industry in recent years, the selection of suitable materials for optical communication components, and the design of components and modules have become the key elements of whether the products launched by each company are competitive. Among them, the selection of materials for optical communication components Although traditional glass materials have excellent optical properties, they are gradually replaced by emerging polymer materials due to their shortcomings such as fragility and difficulty in processing. Polymer materials have the advantages of high impact strength and good processability. They can be produced by extrusion or injection molding, which can help mass production and reduce costs...
