Abstract(in English) In order to achieve a cost reduction in discrete passive components (isolators, WDMs with thin film and so on), we have developed a novel collimator with a D-lens, which is machined into a drum-like shape from a complete spherical lens. A typical optical passive component consists of two collimators. In a conventional collimator, optical fiber in a precision glass capillary is precisely aligned with a GRIN-lens. In contrast to conventional alignment, we have developed a self-alignment structure using glass-ceramic capillary and D-lens instead of a glass capillary and GRIN-lens. We report on the details of D-lens and D-lens collimator in this paper.
