本発明は通信、光学部品として用いられるフィルタ付き
光導波路の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an optical waveguide with a filter used as a communication or optical component.
「従来の技術ｊ
既知の通り、光分波、光合波などを必要とする通信系、
光学系では、多数枚のフィルタを高精度で配列した光導
波路を用いている。``Conventional technology j As is known, communication systems that require optical demultiplexing, optical multiplexing, etc.
The optical system uses an optical waveguide in which a large number of filters are arranged with high precision.
従来、こうしたフィルタ付き光導波路を製造する手段と
して、プリズムの所定面にフィルタを張りつけ、さらに
そのフィルタ付きプリズムを適当な手段で組み合わせる
方法がとられている。Conventionally, as a means of manufacturing such a filtered optical waveguide, a method has been used in which a filter is pasted on a predetermined surface of a prism, and the filtered prisms are further assembled by appropriate means.
「発明が解決しようとする叫題点」
ｉ：、述した従来例の場合、プリズムの加工がコスト高
となるばかりか、傾斜面をもつｔ体形状のプリズムでは
、その所定面へのフィルタの張りっけがむずかしく、フ
ィルタ付きプリズムの組み合わせにも難度がともなう。``Problem to be solved by the invention'' i: In the case of the conventional example described above, not only is the processing of the prism expensive, but also the prism has a T-shape with an inclined surface, and it is difficult to attach a filter to a predetermined surface of the prism. It is difficult to attach, and the combination of filtered prisms is also difficult.
そのためフィルタの位置、角度等につき高精度化が達成
できず、製造に手数がかかりすぎることから、量産性や
価格についても満足できないものとなっている。As a result, it is not possible to achieve high precision in the position, angle, etc. of the filter, and the manufacturing process is too labor-intensive, making it unsatisfactory in terms of mass productivity and price.
本発明は上記の問題点に鑑み、高精度、製造易度、低価
格などを満足させることのできるフィルタ付き光導波路
の製造方法を提供しようとするものである。In view of the above-mentioned problems, the present invention aims to provide a method for manufacturing an optical waveguide with a filter that can satisfy high precision, ease of manufacture, low cost, etc.
Ｉ問題点を解決するための手段ｊ

これら板ガラスの任意板面に密着するフィルタとにより
積層体をつくり、その後、板ガラスの板面に対し非直角
で交差する方向の切断手段により、当該積層体を所望の
厚さで切断することを積層している。Means for Solving Problem I j The method for manufacturing an optical waveguide with a filter according to the present invention comprises: a plurality of glass plates whose front plate surface and rear plate surface are parallel to each other;
A laminated body is created by making a laminate with a filter that is in close contact with any plate surface of the plate glass, and then the laminated body is cut to a desired thickness by a cutting means in a direction that is non-perpendicular to and intersects with the plate surface of the plate glass. are doing.

存して各フィルタの平行間隔精度が確保できるとともに
、各板ガラスの厚さにより各フィルタ相互の間隔（位置
）も高精度で定まる。In this case, the laminate can be easily produced because it is only necessary to attach the filter to the surface of the plate glass and laminate the plate glasses with filters, and the accuracy of the parallel spacing of each filter can be ensured by relying on the plate glass whose both sides are parallel. At the same time, the mutual spacing (position) of each filter is also determined with high precision depending on the thickness of each plate glass.
その後、板ガラスの板面に対し非直角で交差する方向の
切断手段により、上記積層体を所望の厚さで切断するが
、当該切断工程により得られた切断物の場合、その切断
面に対し各フィルタが傾斜状態となる。Thereafter, the above-mentioned laminate is cut to a desired thickness using a cutting means in a direction perpendicular to the plate surface of the plate glass. The filter becomes tilted.
この際のフィルタの傾斜角度は積層体切断時のと配交差
角（非直角）により任意に設定でき、当該切断も難度な
く高精度で行ない得る。The inclination angle of the filter at this time can be arbitrarily set depending on the alignment angle (non-perpendicular) when cutting the laminate, and the cutting can also be performed with high precision without difficulty.
かくして製造されたフィルタ付き光導波路の場合、各フ
ィルタの平行度、位置、傾斜角度等がいずれも高精度と
なる。In the case of the filtered optical waveguide manufactured in this manner, the parallelism, position, inclination angle, etc. of each filter are all highly accurate.
もちろん本発明ではａ層工程、切断工程など、少ない工
程でフィルタ付き光導波路が製造でき、１つの積層体か
ら多数個のフィルタ付き光導波路が得られるから、歩留
まりの低下もない。Of course, in the present invention, an optical waveguide with a filter can be manufactured with a small number of processes such as an a-layer process and a cutting process, and a large number of optical waveguides with a filter can be obtained from one laminate, so there is no decrease in yield.
