摘要

PROBLEM TO BE SOLVED: To provide a surface-emitting laser having a wide wavelength variable band.SOLUTION: The surface-emitting laser includes a first reflecting mirror 102, a second reflecting mirror 116, and an active layer 104 arranged between the first reflecting mirror 102 and the second reflecting mirror 116. A gap is formed between the second reflecting mirror 116 and the active layer 104. The oscillation wavelength of the surface-emitting laser is variable. The second reflecting mirror 116 includes a beam 108 made of a single-crystal semiconductor and a dielectric multilayer film 110 supported by the beam 108. The dielectric multilayer film 110 is arranged in an opening 118 formed in the beam 108.SELECTED DRAWING: Figure 1
