| 英文摘要 | In an optical coupling unit having an optical coupler adapted to couple a light beam from a light-emitting element to an optical fiber, the aberration of the lens is decreased to improve the efficiency of coupling of the light beam from the light-emitting element to the optical fiber. A silicon crystal having a high refractive index is used as a lens material to realize an optical system of low aberration. |
