PROBLEM TO BE SOLVED: To provide an optical fiber component capable of preventing disconnection of an optical fiber even if the optical fiber is connected to an optical circuit as it is curved.SOLUTION: An optical fiber component 2 comprises: a holding member 23 that holds an optical fiber 26 in such a manner that an end face 26A of the optical fiber 26 is arranged on an end face 23A side thereof and the optical fiber 26 extends on an end face 23B thereof; a reinforcement member 24 that is arranged in an extension direction D1 of the optical fiber 26 relative to the holding member 23 and fixed to the holding member 23; and a bend restricting part 25 that is fixed to the reinforcement member 24 and projects farther than the end face 23B and in which the projecting part curves at a predetermined curvature radius in the extension direction D1 of the optical fiber 26.SELECTED DRAWING: Figure 1

Description

本開示は、光回路に光ファイバを接続する光ファイバ部品に関する。   The present disclosure relates to an optical fiber component that connects an optical fiber to an optical circuit.

光通信装置の小型化に伴い、光回路に接続された光ファイバを湾曲してパッケージ内に配線する構成が採用されるようになっている。そのため、光回路に接続された光ファイバが偏波保持特性の劣化が生じる許容曲率半径以下に湾曲しないようにするための技術が提案されている（例えば、特許文献１参照。）。特許文献１は、光ファイバの湾曲部分の外側に支持面を配置し、支持面と光ファイバとを接着剤で固定する。   Along with the miniaturization of optical communication devices, a configuration is adopted in which an optical fiber connected to an optical circuit is bent and wired in a package. Therefore, a technique has been proposed for preventing the optical fiber connected to the optical circuit from being bent below the allowable curvature radius at which the polarization maintaining characteristic is deteriorated (see, for example, Patent Document 1). In Patent Document 1, a support surface is disposed outside a curved portion of an optical fiber, and the support surface and the optical fiber are fixed with an adhesive.

特許文献１は、支持面の内側に光ファイバが接着剤で固定されるため、組み立て中に光ファイバに他の部品が接触するなどして光ファイバに引っ張り応力がかかった場合、接着剤で固定されなくなった部分で光ファイバの断線が生じる可能性がある。   In Patent Document 1, since the optical fiber is fixed with an adhesive inside the support surface, if tensile stress is applied to the optical fiber due to other parts coming into contact with the optical fiber during assembly, the optical fiber is fixed with the adhesive. There is a possibility that the optical fiber is broken at the portion where the operation is not performed.

In addition, this indication is not limited to embodiment shown below. These embodiments are merely examples, and the present disclosure can be implemented in various modifications and improvements based on the knowledge of those skilled in the art. In the present specification and drawings, the same reference numerals denote the same components.

（実施形態１）
図１に、本実施形態に係る光ファイバ部品の第１の概略構成を示す。本実施形態に係る光ファイバ部品２は、光ファイバ２６の端面２６Ａを光回路３に接続する部材である。光回路３は、例えば、光導波路や光カプラを備えるフォトニック光回路（以下光回路と称す）である。光ファイバ部品２は、保持部材２３と、補強部材２４と、曲げ規制部２５とを備える。 (Embodiment 1)
In FIG. 1, the 1st schematic structure of the optical fiber component which concerns on this embodiment is shown. The optical fiber component 2 according to the present embodiment is a member that connects the end face 26 </ b> A of the optical fiber 26 to the optical circuit 3. The optical circuit 3 is, for example, a photonic optical circuit (hereinafter referred to as an optical circuit) including an optical waveguide and an optical coupler. The optical fiber component 2 includes a holding member 23, a reinforcing member 24, and a bending restricting portion 25.

本開示は、保持部材２３の一端である端面２３Ａに光ファイバ２６の端面２６Ａが配置され、保持部材２３の他端である端面２３Ｂに光ファイバ２６が湾曲して延在する。光ファイバ２６の延在方向は、端面２３Ｂにおける光ファイバ２６の周方向のうちの特定方向である。例えば、図１のように、光ファイバ２６の端面２６Ａが光回路３の上面３Ａに接続される場合、光ファイバ２６の延在方向Ｄ１は光回路３の上面３Ａに沿った方向となる。   In the present disclosure, the end surface 26A of the optical fiber 26 is disposed on the end surface 23A that is one end of the holding member 23, and the optical fiber 26 extends in a curved manner on the end surface 23B that is the other end of the holding member 23. The extending direction of the optical fiber 26 is a specific direction in the circumferential direction of the optical fiber 26 on the end face 23B. For example, as shown in FIG. 1, when the end face 26A of the optical fiber 26 is connected to the upper surface 3A of the optical circuit 3, the extending direction D1 of the optical fiber 26 is a direction along the upper surface 3A of the optical circuit 3.

保持部材２３の端面２３Ａは、光回路３の上面３Ａに接合されている。接合は紫外線硬化樹脂等の光硬化樹脂を用いることが好ましい。保持部材２３の端面２３Ａと補強部材２４の端面２４Ａとが同一面上に配置され光回路３の上面３Ａに接合されることが好ましい。光回路３の上面３Ａとの接合面積が大きくなるため、接合強度を補強することができる。補強部材２４は、光ファイバ２６および光ファイバ２６を固定した保持部材２３と共に端面研磨されてもよい。   An end surface 23 </ b> A of the holding member 23 is bonded to the upper surface 3 </ b> A of the optical circuit 3. It is preferable to use a light curable resin such as an ultraviolet curable resin for the bonding. It is preferable that the end surface 23 </ b> A of the holding member 23 and the end surface 24 </ b> A of the reinforcing member 24 are arranged on the same plane and joined to the upper surface 3 </ b> A of the optical circuit 3. Since the bonding area with the upper surface 3A of the optical circuit 3 is increased, the bonding strength can be reinforced. The reinforcing member 24 may be end-face polished together with the optical fiber 26 and the holding member 23 to which the optical fiber 26 is fixed.

光ファイバ２６の端面２６Ａでの光軸と保持部材２３の端面２３Ａとのなす角度αは、９０°ではないことが好ましく、これにより端面２６Ａでの反射による減衰を防ぐことができる。また、角度αは、光回路３からの光入出射方向に合わせた角度であることが好ましい。   The angle α formed between the optical axis at the end face 26A of the optical fiber 26 and the end face 23A of the holding member 23 is preferably not 90 °, thereby preventing attenuation due to reflection at the end face 26A. In addition, the angle α is preferably an angle matched to the light incident / exit direction from the optical circuit 3.

図２のように、光ファイバ２６の端面２６Ａが光回路の端面３Ｂに接続される場合、光ファイバ２６の延在方向Ｄ１は光回路３の上面３Ａに略垂直な方向となる。   As shown in FIG. 2, when the end surface 26 </ b> A of the optical fiber 26 is connected to the end surface 3 </ b> B of the optical circuit, the extending direction D <b> 1 of the optical fiber 26 is substantially perpendicular to the upper surface 3 </ b> A of the optical circuit 3.

保持部材２３は、光ファイバ２６を保持する部材であり、キャピラリやＶ溝などの任意の光部品を用いることができる。光ファイバ２６の側面２６Ｃが保持部材２３に覆われ、これによって保持部材２３が光ファイバ２６を保持する。端面２３Ａが光回路３に固定され、光ファイバ２６の端面２６Ａと光回路３の光導波路や光カプラが結合される。   The holding member 23 is a member that holds the optical fiber 26, and any optical component such as a capillary or a V-groove can be used. The side surface 26 </ b> C of the optical fiber 26 is covered with the holding member 23, whereby the holding member 23 holds the optical fiber 26. The end face 23A is fixed to the optical circuit 3, and the end face 26A of the optical fiber 26 is coupled to the optical waveguide or optical coupler of the optical circuit 3.

補強部材２４は、保持部材２３に対し、光ファイバ２６の延在方向Ｄ１に配置されている。補強部材２４の側面２４Ｃの少なくとも一部は、保持部材２３の側面２３Ｃに固定されている。補強部材２４と保持部材２３とが固定されている面積は大きいことが好ましく、延在方向Ｄ１側に位置する保持部材２３の側面２３Ｃの全面、或いは、延在方向Ｄ１と逆方向側に位置する補強部材２４の側面２４Ｃの全面が固定されていることが好ましい。   The reinforcing member 24 is disposed in the extending direction D1 of the optical fiber 26 with respect to the holding member 23. At least a part of the side surface 24 </ b> C of the reinforcing member 24 is fixed to the side surface 23 </ b> C of the holding member 23. The area where the reinforcing member 24 and the holding member 23 are fixed is preferably large, and is located on the entire side surface 23C of the holding member 23 located on the extending direction D1 side or on the opposite side to the extending direction D1. It is preferable that the entire side surface 24C of the reinforcing member 24 is fixed.

曲げ規制部２５は、少なくとも一部が補強部材２４に固定されている。例えば、曲げ規制部２５は、補強部材２４の側面２４Ｃ又は端面２４Ｂに固定される。曲げ規制部２５は、図１に示すように、曲げ規制部２５の光回路３側に配置される面が補強部材２４の端面２４Ｂに固定されていることが好ましい。   At least a part of the bending restricting portion 25 is fixed to the reinforcing member 24. For example, the bending restricting portion 25 is fixed to the side surface 24C or the end surface 24B of the reinforcing member 24. As shown in FIG. 1, the bend restricting portion 25 is preferably fixed to the end surface 24 </ b> B of the reinforcing member 24 at the surface disposed on the optical circuit 3 side of the bend restricting portion 25.

曲げ規制部２５は、保持部材２３の端面２３Ｂよりも保持部材２３の端面２３Ｂ側に突出し、当該突出している部分に曲面２５Ａが備わる。曲面２５Ａは、光ファイバ２６の延在方向Ｄ１に沿った予め定められた曲率半径で湾曲している。予め定められた曲率半径は、光ファイバ２６が引っ張られたとき、光ファイバ２６が過剰に曲がって折れることを防止することの可能な曲率半径である。例えば、光ファイバ２６の許容曲げ半径が３０ｍｍであるならば、曲面２５Ａの所定曲げ半径は３０ｍｍ以上である。光ファイバ２６は曲げ規制部２５に接着剤により固定されていることが好ましい。   The bending restricting portion 25 protrudes to the end surface 23B side of the holding member 23 from the end surface 23B of the holding member 23, and the protruding portion is provided with a curved surface 25A. The curved surface 25A is curved with a predetermined radius of curvature along the extending direction D1 of the optical fiber 26. The predetermined radius of curvature is a radius of curvature that can prevent the optical fiber 26 from being excessively bent and broken when the optical fiber 26 is pulled. For example, if the allowable bending radius of the optical fiber 26 is 30 mm, the predetermined bending radius of the curved surface 25A is 30 mm or more. The optical fiber 26 is preferably fixed to the bending restricting portion 25 with an adhesive.

補強部材２４の熱膨張係数は、温度特性や長期信頼性の点から、保持部材２３の熱膨張係数と等しいことが好ましい。例えば、補強部材２４の材質は保持部材２３と同じ材質であることが好ましい。保持部材２３がガラスキャピラリであった場合、補強部材２４は、保持部材２３と同じガラス素材、もしくはガラス素材と同等の熱膨張係数を有するセラミック素材又はプラスチック素材にすることが好ましい。   The thermal expansion coefficient of the reinforcing member 24 is preferably equal to the thermal expansion coefficient of the holding member 23 from the viewpoint of temperature characteristics and long-term reliability. For example, the reinforcing member 24 is preferably made of the same material as the holding member 23. When the holding member 23 is a glass capillary, the reinforcing member 24 is preferably made of the same glass material as the holding member 23 or a ceramic material or a plastic material having a thermal expansion coefficient equivalent to that of the glass material.

曲げ規制部２５は、補強部材２４とは別部材であることが好ましく、例えばガラスやプラスチックを用いることができる。曲げ規制部２５の熱膨張係数は補強部材の熱膨張係数と等しいことが好ましい。曲げ規制部２５と補強部材２４とが同一の部材であってもよく、この場合は曲げ規制部２５及び補強部材２４を一体とし、同時に形成することができる。   The bending restricting portion 25 is preferably a separate member from the reinforcing member 24. For example, glass or plastic can be used. The thermal expansion coefficient of the bending restricting portion 25 is preferably equal to the thermal expansion coefficient of the reinforcing member. The bending restricting portion 25 and the reinforcing member 24 may be the same member. In this case, the bending restricting portion 25 and the reinforcing member 24 can be integrated and formed simultaneously.

図１及び図２では、保持部材２３の端面２３Ｂと補強部材２４の端面２４Ｂが、同一平面に配置されている例を示したが、本開示はこれに限定されない。例えば、光ファイバ２６の端面２６Ａが光回路の上面３Ａに接続される場合、図３に示すように、補強部材２４の端面２４Ｂが保持部材２３の端面２３Ｂよりも光回路３の上面３Ａ側に配置されていてもよい。また、光ファイバ２６の端面２６Ａが光回路の上面３Ａに接続される場合、図４に示すように、保持部材２３の端面２３Ｂが補強部材２４の端面２４Ｂよりも光回路３の上面３Ａ側に配置されていてもよい。   1 and 2 show an example in which the end surface 23B of the holding member 23 and the end surface 24B of the reinforcing member 24 are arranged on the same plane, the present disclosure is not limited to this. For example, when the end surface 26A of the optical fiber 26 is connected to the upper surface 3A of the optical circuit, the end surface 24B of the reinforcing member 24 is closer to the upper surface 3A of the optical circuit 3 than the end surface 23B of the holding member 23, as shown in FIG. It may be arranged. Further, when the end surface 26A of the optical fiber 26 is connected to the upper surface 3A of the optical circuit, the end surface 23B of the holding member 23 is closer to the upper surface 3A of the optical circuit 3 than the end surface 24B of the reinforcing member 24, as shown in FIG. It may be arranged.

図１及び図２では、曲げ規制部２５が保持部材２３の端面２３Ｂと同じ大きさであるが、本開示はこれに限定されない。例えば、図３に示すように、曲げ規制部２５が保持部材２３の端面２３Ｂよりも小さくてもよい。また、図４に示すように、曲げ規制部２５が保持部材２３の端面２３Ｂよりも大きくてもよい。曲げ規制部２５の形状は、任意であり、図３に示すような扇形状であってもよいし、図４に示すような半円形状であってもよい。   In FIGS. 1 and 2, the bending restricting portion 25 has the same size as the end surface 23 </ b> B of the holding member 23, but the present disclosure is not limited to this. For example, as shown in FIG. 3, the bending restricting portion 25 may be smaller than the end surface 23 </ b> B of the holding member 23. Further, as shown in FIG. 4, the bending restricting portion 25 may be larger than the end surface 23 </ b> B of the holding member 23. The shape of the bending restricting portion 25 is arbitrary, and may be a fan shape as shown in FIG. 3 or a semicircular shape as shown in FIG.

また、図１及び図２では、保持部材２３の端面２３Ａと補強部材２４の端面２４Ａとが同一面上に配置される例を示したが、本開示はこれに限定されない。例えば、図５及び図６に示すように、補強部材２４の端面２４Ａと光回路３の上面３Ａ又は端面３Ｂとの間に空隙があってもよい。   1 and 2 show an example in which the end surface 23A of the holding member 23 and the end surface 24A of the reinforcing member 24 are arranged on the same plane, the present disclosure is not limited to this. For example, as shown in FIGS. 5 and 6, there may be a gap between the end surface 24 </ b> A of the reinforcing member 24 and the upper surface 3 </ b> A or the end surface 3 </ b> B of the optical circuit 3.

以上説明したように、本開示は、光回路３に接続された光ファイバ２６を湾曲してパッケージ内に配線する場合であっても、光ファイバ２６の湾曲する側に凸面２５Ａが配置されているため、組み立て中における光ファイバ２６の断線を防ぐことができる。なお、本開示は、光回路３に限らず、光ファイバ部品２が接続され得る任意の光部品に接続する場合であっても、同様の効果が得られる。   As described above, according to the present disclosure, even when the optical fiber 26 connected to the optical circuit 3 is bent and wired in the package, the convex surface 25A is arranged on the curved side of the optical fiber 26. Therefore, disconnection of the optical fiber 26 during assembly can be prevented. Note that the present disclosure is not limited to the optical circuit 3, and the same effect can be obtained even when the optical fiber component 2 is connected to an arbitrary optical component.

FIG. 7 is a top view, a side view, and an AA ′ sectional view showing an example of the optical fiber component according to the present embodiment. The optical fiber component according to this embodiment includes a flat plate-shaped reinforcing member 24. For example, an adhesive is used to fix the holding member 23 and the reinforcing member 24.

図７では、一例として、複数の光ファイバ２６を保持するキャピラリが保持部材２３として用いられている例を示す。図７では、４本の光ファイバ２６を保持する楕円形のキャピラリの例を示すが、キャピラリの断面形状は楕円形に限らず、円形断面や円形の断面の一部を切除したＤ形や、矩形、長円等の断面形状であってもよい。キャピラリの複数の光ファイバ挿入孔は、放射状のものであっても、互いに平行な孔であってもよい。また、本開示はこれに限定されない。例えば、本実施形態の保持部材２３は、図８に示すように、複数の光ファイバ２６を保持するＶ溝を保持部材２３として用いてもよい。また、保持部材２３内に配置されている光ファイバ２６は１列に限定されず、２列以上であってもよい。   FIG. 7 shows an example in which a capillary for holding a plurality of optical fibers 26 is used as the holding member 23 as an example. In FIG. 7, an example of an elliptical capillary holding four optical fibers 26 is shown, but the cross-sectional shape of the capillary is not limited to an elliptical shape, a circular shape or a D-shape obtained by cutting a part of the circular shape, A cross-sectional shape such as a rectangle or an ellipse may be used. The plurality of optical fiber insertion holes of the capillary may be radial or parallel to each other. Further, the present disclosure is not limited to this. For example, as shown in FIG. 8, the holding member 23 of this embodiment may use a V-groove that holds a plurality of optical fibers 26 as the holding member 23. Further, the optical fibers 26 arranged in the holding member 23 are not limited to one row, and may be two or more rows.

図７では、一例として、端面２３Ｂ及び端面２４Ｂが同一面上に配置される例を示したが、本開示はこれに限定されない。例えば、図９及び図１０に示すように、補強部材２４の端面２４Ｂに切欠き２４Ｌを設け、切欠き２４Ｌに曲げ規制部２５を配置してもよい。切欠き２４Ｌの幅Ｗ２４Ｌは、任意であるが、補強部材２４の端面２４Ｂに光ファイバ２６が接触しない程度の幅を有することが好ましい。 In FIG. 7, as an example, an example in which the end surface 23B and the end surface 24B are arranged on the same surface is shown, but the present disclosure is not limited thereto. For example, as shown in FIGS. 9 and 10, a cutout 24 </ b> L may be provided in the end surface 24 </ b> B of the reinforcing member 24, and the bending restricting portion 25 may be arranged in the cutout 24 </ b> L.
