Abstract
A structure for connecting a plastic optical fiber to a light receiving element. The plastic optical fiber has an end face that emits light. The light receiving element has a light receiving face that has a smaller surface than that of the end face of the plastic optical fiber. The structure includes a conical outer surface, a fiber-side surface, and an element-side face. The diameter of the structure decreases gradually from the fiber-side face towards the element-side face. The structure is adapted for interconnecting the end face of the plastic optical fiber and the light receiving face of the light receiving element where the connection loss therebetween is minimized.
