| 英文摘要 | A compact, inexpensive laser diode module having a depolarizer function of converting linearly polarized light into unpolarized light. The laser diode module includes a laser diode; a polarization-maintaining optical fiber arranged so that an axis of polarization of the fiber forms an angle of 45 DEG with respect to a plane of polarization of incident light, the fiber having a length set so that an optical path difference between two polarization modes of transmitted light is greater than a coherence length of the incident light; and an optical coupling element for coupling emitting light from the laser diode to the polarization-maintaining optical fiber. |
