Abstract

PURPOSE:To couple the semiconductor laser and single mode optical fiber at high efficiency, by transforming the laser exit light into parallel lights of large diameter by means of the lens system, and leading the parallel lights into a single mode optical fiber by way of a fiber lens. CONSTITUTION:An exit light emitted from a semiconductor laser 1 is transformed into parallel lights by a focusing type fiber lens 6 through a very small diameter glass rod 2, and enters a focusing type optical fiber lens 7 affixed to the entry end plane of a single mode optical fiber 3 to be reduced into a core 4 of the single mode optical fiber 3. By setting the diameter of the parallel lights sufficiently large as compared with the radius of the propagation mode of the single mode optical fiber, the aligning precision of the single some optical fiber and semiconductor laser may be alleviated.
