Abstract

PURPOSE:To make possible the bonding operation, which is excellent in bonding efficiency and which is reduced in mode conversion, by forming a guide tube with core circumferential portion, which has its refractive index gradually increased from its cover layer to the center, and with a core center portion which has a preset larger refractive index.
