The element unit 61 of the optical device 13 is a light emitting unit when the optical device 13 is a light emitting element, and is a light receiving unit when the optical device 13 is a light receiving element.

The terminal portion 62 of the optical device 13 includes a short terminal portion 63 disposed below the element portion 61 and a long terminal portion 64 disposed on the side of the element portion 61.

In the photoelectric conversion module 15 including the photoelectric conversion component 11 described above, four optical transmission paths A are formed as shown in FIG. 5, and the optical device 13 and the glass are formed via these optical transmission paths A. Optical transmission is performed with the fiber 44.
When light is transmitted from the optical device 13 made of a light emitting element to the glass fiber 44, the light emitted from the element portion 61 of the optical device 13 and irradiated to the second light transmitting portion 22 is collected by the internal lens surface 31. The light passes through the first light transmitting portion 21, is condensed again by the external lens surface 32, and enters the core 44 a of the glass fiber 44.

  In addition, when light is transmitted from the glass fiber 44 to the optical device 13 including a light receiving element, the light emitted from the core 44 a of the glass fiber 44 is condensed by the external lens surface 32 and passes through the first light transmitting portion 21.

On the transmission path, the first light transmitting portion 21 is formed on the opposite side of the inner lens surface 31 from the optical device 13. In addition, the second light transmissive part formed between the optical device 13 and the first light transmissive part has a refractive index larger than that of the first light transmissive part 21. In the optical transmission path A passing through the optical axis of the internal lens surface 31 of the photoelectric conversion component 11, optical transmission is performed between the optical device 13 and the glass fiber 44. Therefore, the optical fiber is inserted into the fiber hole of the ferrule and fixed. Compared with the structure, the independence of the glass fiber 44 can be enhanced. Further, the light transmitted through the optical transmission line A is transmitted by the internal lens surface 31 provided at the boundary surface between the first light transmitting part 21 and the second light transmitting part 22 having a refractive index larger than that of the first light transmitting part 21. Since light can be condensed well, light transmission can be performed with good optical coupling efficiency.

Thereby, at the time of mounting the glass fiber 44, it is possible to eliminate a decrease in optical coupling efficiency due to generation of shavings and a decrease in yield due to contact with the optical device 12. That is, the yield can be increased and good optical coupling efficiency can be obtained.
Further, since the first light transmitting portion 21 is provided with the external lens surface 32 on the surface opposite to the optical device 13 with respect to the internal lens surface 31, the internal lens surface 31 and the external lens surface 32 are doubled. The optical coupling efficiency can be further improved by the lens structure.

  Next, the case where the photoelectric conversion component 11 is manufactured will be described for each process.

The 1st translucent part 21 is integrally molded. At this time, pin-shaped die dies are arranged at positions where the hole 23 and the opening 24 are formed, and the respective die dies are extracted at the time of demolding.

(Optical device bonding process)
Next, as illustrated in FIG. 6B, the optical device 13 is bonded to the device fixing surface 11 a on the opening side of the hole 23 in the molded first light transmitting portion 21. Specifically, the device fixing surface 11 a and the element surface 13 a of the optical device 13 are abutted, and the electrode 20 and the terminal portion 62 are conductively connected by the bump 70.

(Second translucent part molding process)
Then, as shown in FIG.6 (c), the 2nd translucent part 22 is shape | molded by filling the hole part 23 of the 1st translucent part 21 with the 2nd transparent material of a molten state, and making it harden | cure. . Here, the second filling material filled in the hole portion 23 also enters the gap between the first light transmitting portion 21 and the optical device 13 and is cured so as to cover the periphery of the optical device 13. Thereby, the optical device 13 is covered with the second transparent material that forms the second light transmitting portion 22, and the connection portion between the electrode 20 of the photoelectric conversion component 11 and the terminal portion 62 of the optical device 13 is formed. Reinforced. Even if air bubbles are included in the second transparent material filled in the hole portion 23, the air bubbles are guided to the opening portion 24 of the first light transmitting portion 21 and discharged from the opening portion 24 to the outside. . As a result, the hole 23 is filled with the second transparent material without remaining bubbles, and a good second light-transmitting portion 22 is molded.

  And according to said manufacturing method of photoelectric conversion components, the photoelectric conversion component 11 which does not fall in the yield at the time of mounting of the glass fiber 44, and can obtain favorable optical coupling efficiency is manufactured smoothly. can do.

  In the above embodiment, the opening 24 connected to the hole 23 is formed in the first light transmitting portion 21, but as shown in FIGS. 7 and 8, the upper surface of the first light transmitting portion 21 and the device fixing surface are formed. You may form the slit 80 connected to 11a. According to the first light transmitting part 21 having such a slit 80, the bubbles of the second transparent material to the hole part 23 can be discharged well from the slit 80, and the first light transmitting part 21 At the time of molding, the die for forming the hole 23 and the slit 80 can be integrated and removed in the same direction, and the efficiency of the molding operation can be increased.

Moreover, although the said embodiment demonstrated and demonstrated what has the four optical transmission paths A as the photoelectric conversion component 11, the number of the optical transmission paths A is not limited to four.
Further, the external lens surface 32 may not be formed depending on conditions such as the refractive index of the first light transmitting portion 21, the refractive index of the second light transmitting portion 22, the radius of curvature of the internal lens surface 31, and the like. In some cases, the array 14 is disposed in contact with the photoelectric conversion component 11.

  Using a plurality of types of photoelectric conversion parts with different materials and dimensions, the optical coupling efficiency in the optical transmission path was measured.

(Test method)
A light emitting element (VCSEL) serving as a light source was attached to the device fixing surface of each photoelectric conversion component, and the optical coupling efficiency when light was emitted by this light emitting element was measured.
The light-emitting element that serves as the light source has a light-emitting portion diameter of 0.0014 mm with reference to actual measurement values, a uniform near-field pattern (NFP), and a far-field pattern (FFP) having the characteristics shown in FIG. Was used.

(Test results)
The optical coupling efficiency was 0.60 in Example 1, 0.86 in Example 2, and 0.92 in Example 3, and good optical coupling efficiencies of 0.6 or more were obtained. This is considered to be because the optical coupling efficiency is improved by forming the second light-transmitting portion to form a double lens structure of the inner lens surface and the outer lens surface. Further, from this result, it is considered that if the width of the refractive index of the usable transparent material is increased, the optical coupling efficiency can be further improved, and a good optical coupling efficiency of 0.9 or more can be easily obtained.
In Comparative Example 1, the optical coupling efficiency was as low as 0.3. This is presumably because the optical coupling efficiency was not improved because there was no second light transmitting part and only the external lens surface was provided.
