PURPOSE: An optical transmission device using an optical fiber is provided to increase an amount of incident light by improving light collection efficiency and state by aligning phase of light by including the rare earth element. CONSTITUTION: A light source(105) includes an LED, an LD and an OLED A concave mirror(101) reflects output light from the light source to a specific direction. A light collection unit(110) collects light reflected from the concave mirror. The light collection unit transmits the collected light and emits. An optical fiber(104) receives the emitted light at the end of one side and transmits to the other end. |
