Abstract

Provided is an optical module wherein a resin material is prevented from entering an optical path and a photoelectric conversion element is fixed with the highly reliable resin material, while ensuring transparency of the optical path. An optical module (100) is provided with a photoelectric conversion element (31), and an optical ferrule (33) wherein the photoelectric conversion element (31) is arranged on one end surface (43) and an optical fiber inserting hole (45) is formed at a position corresponding to an active layer (39) of the photoelectric conversion element (31) is formed so as to penetrate the optical ferrule. A resin material (49) is applied and cured between the photoelectric conversion element (31) and the optical ferrule (33). An opening section (51) of an optical fiber inserting hole (45) formed on the one end surface (43) of the optical ferrule (33) is covered with a transparent substance (53) which is brought into contact with the active layer (39) for preventing the resin material (49) from entering. The transparent substance (53) can be in a state of sheet or grease. The sheet or the grease can be separately arranged corresponding to each of the optical fiber inserting holes (45).

Description

technical field [0001] The present invention relates to an optical module in which an optical fiber and a photoelectric conversion element are directly optically coupled and an assembly method thereof, and particularly relates to an improved technique for filling a structure of a resin material in a gap between a photoelectric conversion element and an optical ferrule. Background technique [0002] With the increase in the speed of signals between LSIs, it is difficult to eliminate noise and increase power consumption in electrical transmission. Therefore, in recent years, attempts have been made to perform transmission between LSIs by optical communication that has almost no electromagnetic barrier and frequency-dependent loss. For example, the photoelectric conversion head (optical module) disclosed in Patent Document 1 has: a light emitting element (for example, VCSEL: Vertical Cavity Surface Emitting Laser, etc.) or a photosensitive element (photoelectric conversion elem...
