Abstract: An optical coupling apparatus including a light emitting diode, a lens, an optical isolator and an optical fiber disposed on a common optical axis is improved in the optical coupling efficiency. The individual optical elements are roughly adjusted in the respective positions and fixed, and then a precise and fine adjustment is effectuated by plastically deforming a portion of a holder for supporting the lens or the optical isolator and/or by adjusting inclination of the holder. The holder imparted with the fine adjustment capability can be implemented as a lens holder.
