| 英文摘要 | A fiber optic apparatus interfaces a single mode fiber into free space for coupling to active or passive devices with a collimated or parallel ray beam. This is accomplished by splicing or fusing to the end of the single mode fiber one of two types of lenses. The first type uses a graded index fiber which is cut to an odd multiple of a quarter wavelength of the light beam. The second technique is to use a step index fiber with a curved end forming a lens having a length relative to a hypotenuse line along the angle of emission of a single mode fiber to subtend half of the diameter of the core of the step index fiber. This, depending on the curvature at the end of the step index fiber, will produce either a collimated beam or a beam focused to a point. |
