Abstract
Disclosed is an optical fiber collimator including a single-mode fiber and a graded-index multi-mode fiber. The graded-index multi-mode fiber is spliced with the single-mode fiber and has a predetermined length so as to collimate light rays. The waveform of the light rays in the graded-index multi-mode fiber has a period P during the transmission and the length of the graded-index multi-mode is substantially 0.25.times.N.times.P, wherein N is a positive odd number.
