| 英文摘要 | PURPOSE:To suppress the noise to transmit signals of high quality by leading the output light of a laser diode LD to a multimode fiber, whose end face is inclined, through a single mode fiber whose one end is a vertical end face and is coated with a reflecting mirror. CONSTITUTION:The laser beam from an active layer 101 of an LD1 placed on a stem 2 is led to a core 102 of a short single mode pigtail fiber 3, whose one end is worked to a taper ending ball and the other end is coated with a mirror 4 having a prescribed reflection factor, through a taper ending ball 103. The light emitted from the mirror end 4 of the fiber 3 is led to a core 10 of a multimode fiber 5 for transmission, whose end face is inclined, and is transmitted. Thus, the wavelength shift of the LD due to LD direct current modulation is suppressed to suppress the signal distortion for multimode fiber transmission, and the LD noise is oscillated in the single mode to reduce the LD noise, and the modal noise is suppressed. |
