| 英文摘要 | The present invention provides an optical transmitter for transmitting an optical signal using an optical fiber as a transmission medium. The optical transmitter comprises: a substrate having a through hole; and a light-emitting element disposed on a rear surface of the substrate and having a light-emitting portion. The through hole has an inner wall. The through hole has an inside diameter increasing from a rear surface side of the substrate toward a front surface side thereof. The light-emitting element is disposed so that the light-emitting portion is exposed within the through hole. The light-emitting portion radiates light beams toward a front surface of the substrate. The through hole is such that part of the light beams goes out the through hole without being reflected, and that the other light beams go out the through hole after being reflected from the inner wall thereof. It is possible to increase the coupling efficiency of the optical transmitter by effectively utilizing a light beam light having a wide radiation angle, and improve heat dissipation thereof, while achieving miniaturization and cost reduction of the optical transmitter. |
