SURFACE EMITTING LASER AND OPTICAL COHERENCE TOMOGRAPHY MEASURING APPARATUS USING THE SURFACE EMITTING LASER |
| 摘要 |
A surface emitting laser operable to change a wavelength of emitted light includes a first reflecting mirror, a second reflecting mirror, wherein a cavity is formed between the first reflecting mirror and the second reflecting mirror along the optical axis of the surface emitting laser, an active layer formed within the cavity, a region formed within the cavity, and a movable part situated within the region, the movable part having a refractive index different from a refractive index of the region. The wavelength of emitted light is changeable by changing the position of the movable part along the direction of the optical axis in the region. |
