Summary:Disclosed is an optical coupling system which has a LD element and an optical fiber to be optically coupled with the LD element, where the optical coupling system is filled with optically transparent gel resin with a refractive index higher than that of the air and lower than that of the optical fiber. Further, the surface of the gel resin may be covered with moisture-blocking resin.
