Title:
面発光型レーザ、および前記面発光型レーザを用いた光干渉断層計
Document Type and Number:
Japanese Patent JP6463012
Kind Code:
B2
Abstract:
A surface emitting laser operable to change a wavelength of emitted light includes, a first reflecting mirror (110), a second reflecting mirror (100), 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 (120) formed within the cavity, a region (130) formed within the cavity, and a movable part (140) situated within the region (130), the movable part having a refractive index different from a refractive index of the region (130). The wavelength of emitted light is changeable by changing the position of the movable part (140) along the direction of the optical axis in the region (130).
