도 4는 본 발명에 따른 유기-무기 하이브리드 재료의 열광학계수를 온도변화에 따라 나타낸 것이다.Figure 4 shows the thermo-optic coefficient of the organic-inorganic hybrid material according to the present invention according to the temperature change.

본 발명은 낮은 가격으로 대량 생산이 가능한 광도파로 소자용 유기-무기 하이브리드 재료의 제조방법에 관한 것으로, 새로운 광 특성을 지닌 광도파로 소자용 유기-무기 하이브리드 재료를 합성하는 방법에 관한 것이다. The present invention relates to a method for producing an organic-inorganic hybrid material for an optical waveguide device which can be mass produced at a low price, and to a method for synthesizing an organic-inorganic hybrid material for an optical waveguide device having new optical properties.

현재 광도파로 소자는 통상적으로 반도체 제작 기술이나 MEMS(Micro Electro-Mechanical System)기술을 활용하여 제작되며, 평면 기판상에 광도파로 소자를 제작하는 경우에는 평면 도파로 기술이 이용되고 있다. 또한 이와 같이 제작된 광도파로 소자의 기능을 더욱 집적화하려는 연구가 계속적으로 진행되고 있다.Currently, an optical waveguide device is typically manufactured using a semiconductor fabrication technology or a MEMS (Micro Electro-Mechanical System) technology. In the case of manufacturing an optical waveguide device on a flat substrate, a planar waveguide technology is used. In addition, researches for further integrating the functions of the optical waveguide device manufactured as described above have been continuously conducted.

일반적으로 광도파로 소자의 제조방법을 살펴보면 다음과 같다. 우선, 기판 위에 하부 클래드층을 형성한 다음, 이 하부 클래드층 상부에 코어층을 형성한다. 이어서, 상기 코어층 상부에 포토레지스트층을 형성한 다음, 이를 노광 및 현상하여 포토레지스트 패턴을 형성한다. 얻어진 포토레지스트 패턴을 이용하여 코어층을 식각하여 패터닝한다. 그 후, 패터닝된 코어층 상부에 상부 클래드층을 형성함으로써 광도파로가 완성된다.In general, the manufacturing method of the optical waveguide device is as follows. First, a lower clad layer is formed on a substrate, and then a core layer is formed on the lower clad layer. Subsequently, a photoresist layer is formed on the core layer, and the photoresist pattern is exposed and developed to form a photoresist pattern. The core layer is etched and patterned using the obtained photoresist pattern. Thereafter, the optical waveguide is completed by forming an upper cladding layer over the patterned core layer.

상기 클래드층이나 코어층은 통상적으로 스핀 코팅법에 의해 형성되며, 그 형성재료로는 굴절률이 상이한 실리카나 또는 폴리머가 이용되고 있다. 그러나 코어와 클래드층 형성재료로서 실리카가 이용되는 경우 코어와의 굴절율의 차이는 최대 75%까지 얻어진다. 따라서 이러한 재료를 이용하는 경우에는 광도파로의 규모가 제한되어 초소형 광통신용 수동 소자를 제작하기 어렵다는 문제점이 있다. The cladding layer and the core layer are usually formed by spin coating, and silica or polymers having different refractive indices are used as the forming material. However, when silica is used as the core and cladding layer forming material, the difference in refractive index with the core is obtained up to 75%. Therefore, in the case of using such a material, the size of the optical waveguide is limited, making it difficult to manufacture a passive device for micro optical communication.

가교된 유기-무기 하이브리드 재료를 이용하여 광도파로 소자를 만드는 방법은 다음과 같다.A method of making an optical waveguide device using a crosslinked organic-inorganic hybrid material is as follows.

졸 상태의 생성물을 원하는 기판 위에 떨어뜨린 다음, 원하는 모양을 가진 PDMS 몰드로 덮은 후 UV를 조사하여 경화시키므로 다양한 패턴을 가진 광학 필름을 제조할 수 있다.The product in a sol state is dropped on a desired substrate, and then covered with a PDMS mold having a desired shape, and then cured by irradiating with UV, thereby producing an optical film having various patterns.

본 발명에 따른 포토 패터닝(photo patterning) 과정을 도 2에 나타내었다. The photo patterning process according to the present invention is shown in FIG. 2.

또한 본 발명에 따른 유기-무기 하이브리드 재료는 다이올의 불소기의 양에 따라 굴절율이 변화하는데, 다이올의 양이 증가할수록 굴절율이 감소한다. 즉 다이올인 CF3-BPA의 양이 알콕시실란 즉 3-아크릴록시프로필 트리메톡시실란 양에 대하여 30mol%인 경우에는 굴절율이 1.488인데 반하여, 60mol%인 경우에는 1.484까지 감소하였다. 다이올의 양에 따른 굴절율의 변화를 도 1에 나타내었다. In addition, in the organic-inorganic hybrid material according to the present invention, the refractive index changes depending on the amount of the fluorine group of the diol, and the refractive index decreases as the amount of the diol increases. That is, when the amount of CF 3 -BPA, which is a diol, was 30 mol% based on the amount of alkoxysilane, that is, 3-acryloxypropyl trimethoxysilane, the refractive index was 1.488, whereas when the amount of 60 mol% was reduced to 1.484. The change in refractive index according to the amount of diol is shown in FIG. 1.

본 발명에 따른 유기-무기 하이브리드 물질의 굴절율 및 두께는 프리즘 커플러를 이용하여 측정하였다. 굴절율 및 두께는 유기-무기 하이브리드 물질을 실리콘 기판위에 코팅하여 가교시킨 필름을 1550nm의 파장에서 측정하였다. 프리즘 커플러는 막(Film) 내부에서의 광도파 이론을 응용한 것으로 유전체나 고분자의 굴절률과 두께를 빠르고 정확하게 측정하는 장비이다. The refractive index and thickness of the organic-inorganic hybrid material according to the present invention were measured using a prism coupler. Refractive index and thickness were measured at a wavelength of 1550 nm for a crosslinked film coated with an organic-inorganic hybrid material on a silicon substrate. The prism coupler is an application of the optical waveguide theory inside a film, and is a device for quickly and accurately measuring the refractive index and thickness of a dielectric or a polymer.

본 발명에 따른 유기-무기 하이브리드 재료의 열광학계수는 코팅필름의 온도에 따른 굴절율을 알아보는 것이므로 이 역시 프리즘커플러를 이용하여 측정한다. 프리즘 커플러에 설치되어 있는 자동 온도조절장치를 이용하여 코팅필름의 온도를 변화시켜가면서 굴절율을 측정하였다. 이 역시 1550nm의 파장에서 측정되었다.The thermo-optic coefficient of the organic-inorganic hybrid material according to the present invention is to determine the refractive index according to the temperature of the coating film, which is also measured using a prism coupler. The refractive index was measured while changing the temperature of the coating film using a thermostat installed in the prism coupler. This was also measured at a wavelength of 1550 nm.

아래에서 실시예를 들어 본 발명을 더욱 상세히 설명하나, 본 발명에 따른 실시예들은 여러 가지 다른 형태로 변형될 수 있으며, 본 발명의 범위가 아래에서 상술하는 실시예에 한정되는 것으로 해석되어서는 안 된다.Hereinafter, the present invention will be described in more detail with reference to examples, but the embodiments according to the present invention can be modified in various other forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. do.

APTMS 3g과 졸-겔 반응의 촉매인 바륨하이드록사이드 모노하이드레이트 0.024g을 반응기에 넣고 80℃에서 10분간 먼저 교반한다. 교반 후 상분리와 자체 축합 반응을 막기 위해 CF3-BPA 1.29g을 2시간 동안 연속하여 넣어 준 후 80℃에서 2시간 더 반응시켰다. 반응 후 부산물인 알코올과 촉매는 vacuum heating과 filtering을 하여 제거하였다. 3 g of APTMS and 0.024 g of barium hydroxide monohydrate, which is a catalyst for sol-gel reaction, are added to a reactor and stirred first at 80 ° C. for 10 minutes. After stirring, in order to prevent phase separation and self-condensation reaction, CF 3 -BPA 1.29 g was continuously added for 2 hours, followed by further reaction at 80 ° C for 2 hours. After the reaction, by-product alcohol and catalyst were removed by vacuum heating and filtering.

UV light was irradiated at 15 minutes for photocrosslinking and heat treatment at 150 ° C. for 3 hours. The refractive index of the crosslinked material was measured using a prism coupler. The results are shown in Table 1. In addition, the thermo-optic coefficient of the crosslinked organic-inorganic hybrid material was measured and shown in FIG. 4.

실시예 2Example 2

CF3-BPA를 1.72g 사용한 것 외에는 실시예 1과 동일한 방법으로 실시하였다. 굴절율과 열광학계수를 각각 측정하여 도 1 및 도 4에 나타내었다. The same procedure as in Example 1 was carried out except that 1.72 g of CF 3 -BPA was used. The refractive index and the thermo-optic coefficient were measured, respectively, and are shown in FIGS. 1 and 4.

실시예 3Example 3

CF3-BPA를 2.15g 사용한 것 외에는 실시예 1과 동일한 방법으로 실시하였다. 굴절율과 열광학계수를 각각 측정하여 도 1 및 도 4에 나타내었다.The same procedure as in Example 1 was carried out except that 2.15 g of CF 3 -BPA was used. The refractive index and the thermo-optic coefficient were measured, respectively, and are shown in FIGS. 1 and 4.

실시예 4Example 4

CF3-BPA를 2.58g 사용한 것 외에는 실시예 1과 동일한 방법으로 실시하였다. 굴절율과 열광학계수를 각각 측정하여 도 1 및 도 4에 나타내었다.The same procedure as in Example 1 was carried out except that 2.58 g of CF 3 -BPA was used. The refractive index and the thermo-optic coefficient were measured, respectively, and are shown in FIGS. 1 and 4.

도 4에 따르면 다이올인 CF3-BPA의 양이 증가하면 벤젠기의 양도 증가하게 되어 가교 밀도가 높아지게 되어 온도변화에 따른 굴절율의 변화가 감소한다는 것을 알 수 있다. According to Figure 4 it can be seen that when the amount of CF 3 -BPA, a diol increases, the amount of benzene groups also increases, so that the crosslinking density increases, so that the change in refractive index with temperature changes decreases.
