OPTICAL COUPLING DEVICE AND METHOD FOR MANUFACTURING THE SAME, MASTER FOR THE OPTICAL COUPLING DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: An optical coupling device and a method for manufacturing the same, a master for the optical coupling device and a method for manufacturing the same are provided to increase the mechanical stability of the optical fiber array by forming the supporting jaw between the optical fibers. CONSTITUTION: An optical coupling device includes a substrate(1), a plurality of waveguides(2a), a plurality of supporting grooves(2c) and a clad(2). The plurality of waveguides(2a) is formed on the protrusion parts of the middle portion of the clad(2) in a lengthwise direction. The plurality of supporting grooves(2c) is formed on the depression part placed both ends of the protrusion part of the clad(2) with isolating by the supporting jaw(2b).
