Abstract:
An optical coupling system, comprising:an LD element, andan optical fiber to be optically coupled with said LD element,wherein a region of said optical coupling system between said optical fiber and said LD element is filled with a first optically transparent gel resin with a refractive index higher than that of the air and lower than that of said optical fiber, said first gel resin selected to prevent said first gel resin from flowing out of said space during refractive index alignment, andsaid optical coupling system is surrounded by said first gel resin and an upper surface of said first gel resin is covered only with a conductive, moisture-blocking resin, said conductive, moisture-blocking resin comprising an uncovered upper surface,wherein said conductive, moisture-blocking resin provides said optical coupling system with moisture sealing and electrical shielding.
