Photoelectric hybrid substrate |
摘要 |
A photoelectric hybrid substrate according to the present invention includes an insulating layer that contains a fluororesin as a main component, and conductor layers stacked on two surfaces of the insulating layer. The photoelectric hybrid substrate includes an optical communication mechanism configured to propagate an optical signal in the insulating layer by using reflection at inner surfaces of the conductor layers. |

1. A photoelectric hybrid substrate comprising an insulating layer that contains a fluororesin as a main component; and conductor layers stacked on two surfaces of the insulating layer,
wherein the photoelectric hybrid substrate includes an optical communication mechanism configured to propagate an optical signal in the insulating layer by using reflection at inner surfaces of the conductor layers, and wherein the optical communication mechanism includes a light-emitting portion that emits an optical signal and a light-receiving portion that receives the optical signal, the light-emitting portion includes a through-hole formed in one of the pair of conductor layers and a light-emitting device that emits an optical signal to this through-hole, and the light-receiving portion includes a through-hole formed in one of the pair of conductor layers and a photodetector that receives the optical signal emitted from this through-hole, and a pair of surfaces of the insulating layer exposed in the through-hole of the light-emitting portion and in the through-hole of the light-receiving portion each have an inclined plane that is inclined outwardly in a direction in which the light-emitting portion and the light-receiving portion face each other and extends to the inside of the insulating layer, and the inclined plane has an inclination angle of 64° or more and 68° or less. |
