ABSTRACT:
A quartz-based optical fiber with a lens, wherein a lens shaped in a curved surface is directly formed on an end surface, and its manufacturing method are provided, the quartz-based optical fiber with a lens having a lens section formed by a projecting core shaped in a curved surface on the end surface, the lens section being produced by immersing the end surface section of the quartz-based optical fiber, which consists of a core and a clad having a composition in which the etching speed is higher than that of the core when a hydrofluoric acid solution is applied, in the hydrofluoric acid solution to cause a core shaped in a truncated cone to project from the end surface of said quartz-based optical fiber, then heating and melting the core shaped in the truncated cone and the vicinity thereof, thus changing the truncated cone shape into a curved surface shape.
