Abstract
Description
【発明の詳細な説明】 【発明の利用分野〕 この発明は光通信のための光ファイバに関する。[Detailed description of the invention] [Field of application of the invention] The present invention relates to optical fibers for optical communications.
光ファイバの素材としては従来アクリル樹脂や石英ガラ
スが使用されていたが、石英ガラスは高価であるという
欠点があり、アクリル樹脂は散乱による損失が大である
という欠点があった。Conventionally, acrylic resin and quartz glass have been used as materials for optical fibers, but quartz glass has the disadvantage of being expensive, and acrylic resin has the disadvantage of high loss due to scattering.
この発明はこのような従来の欠点を解消すべく創案され
たもので、散乱による損失がわずかであり、かつ安価に
製作し得る光ファイバを提供することを目的とする。The present invention was devised to overcome these conventional drawbacks, and aims to provide an optical fiber that has little loss due to scattering and can be manufactured at low cost.
この発明に係る光ファイバは、中空パイプの内面に反射
膜を形成したものである。The optical fiber according to the present invention has a reflective film formed on the inner surface of a hollow pipe.
次にこの発明に係る光ファイバの第１実施例を図面に基
づいて説明する。Next, a first embodiment of the optical fiber according to the present invention will be described based on the drawings.
第１図において、光ファイバ１は中空バイブ２よりなり
、内面には反射膜３（図中その厚さを誇張して描いであ
る二）が形成されている。In FIG. 1, an optical fiber 1 consists of a hollow vibrator 2, and a reflective film 3 (2 in the figure, whose thickness is exaggerated) is formed on the inner surface.
このような中空の光ファイバにおいては、光は内部空間

膜３が形成されているので、光が中空バイブ２の外に漏
れるおそれはなく、損失は極めてわずかになる。In such a hollow optical fiber, light propagates through the internal space and scattering is not a problem. Therefore, the degree of freedom in the materials that can be used is greatly expanded, and the cost of optical fibers can be reduced. Furthermore, since the reflective film 3 is formed on the inner surface of the hollow vibrator 2, there is no risk of light leaking out of the hollow vibrator 2, and the loss is extremely small.
中空バイブの素材としては任意の安価な材料、例えば合
成樹脂を使用できる。一方反射膜は、金属例えば銀、ア
ルミニウムなどを蒸着しあるいは塗布するなど種々の素
材を用い種々の方法で形成し得る。Any inexpensive material, such as synthetic resin, can be used as the material for the hollow vibrator. On the other hand, the reflective film can be formed using various materials and by various methods, such as vapor deposition or coating of metals such as silver and aluminum.
なお光ファイバｌの内部を真空にすれば一層損失を低下
し得る。Note that the loss can be further reduced by making the inside of the optical fiber l a vacuum.
第２図はこの発明の第２実施例を示すものであり、中空
バイブ２の端面は透明板４によって塞がれている。この
ような構成においては光フアイバ内部への塵埃の侵入を
防止でき、また内部を真空とする際に、透明板４で機密
シールを構成し得る。FIG. 2 shows a second embodiment of the present invention, in which the end face of the hollow vibrator 2 is closed with a transparent plate 4. As shown in FIG. With such a configuration, it is possible to prevent dust from entering the inside of the optical fiber, and when the inside is evacuated, the transparent plate 4 can form a hermetic seal.
前述のとおり、この発明に係る光ファイバは、中空バイ
ブの内面に反射膜を形成したので、散乱による損失がわ
ずかであり、かつ安価に製作し得るという優れた効果を
有する。As described above, since the optical fiber according to the present invention has a reflective film formed on the inner surface of the hollow vibrator, it has excellent effects in that loss due to scattering is small and it can be manufactured at low cost.
