SURFACE EMITTING LASER AND OPTICAL COHERENCE TOMOGRAPHY USING THE SURFACE EMITTING LASER |
| 摘要 |
A surface emitting laser including a lower reflecting mirror, an active layer, and an upper reflecting mirror in that order, and having a gap portion between the active layer and the upper reflecting mirror, includes a movable portion provided on an optical path of the gap portion and having a refractive index different from a refractive index of the gap portion. A wavelength of light to be emitted is changed by changing positions in an optical-axis direction of at least two of the movable portion, the upper reflecting mirror, and the lower reflecting mirror. |

1. A surface emitting laser including a lower reflecting mirror, an active layer, and an upper reflecting mirror in that order, and having a gap portion between the active layer and the upper reflecting mirror, the surface emitting laser comprising:
a movable portion provided on an optical path of the gap portion and having a refractive index different from a refractive index of the gap portion, wherein a wavelength of light to be emitted is changed by changing positions in an optical-axis direction of at least two of the movable portion, the upper reflecting mirror, and the lower reflecting mirror. |
