PROBLEM TO BE SOLVED: To provide a highly efficient semiconductor near-field light source which can be arrayed and can be manufactured easily, a method for manufacturing the light source, and a near-field optical system using the light source. SOLUTION: A semiconductor near-field light source is constituted by laminating a compound semiconductor layer constituted in a triangular pyramid structure using the regular triangular exposed surface of a compound semiconductor substrate 11 as one face on the exposed surface of the substrate 11 and the triangular pyramid structure has a surface emission type laser structure 12 containing at least a pair of multilayered semiconductor film reflecting mirrors and an active layer laminated in the thickness direction. A very small opening 13 having a size at the level of the oscillating wavelength of the laser 12 is formed near the apex of the triangular pyramid structure and the light oscillated form the laser 12 is introduced to the opening 13 and generates near-field light. |
