    摘要: One objective of the present invention is to provide a laser device which is capable of scanning beams of a laser light of high output power at a high speed without using mechanical scanning mechanisms. A plurality of the upper electrodes 33 is linearly arranged in the photonic crystal laser provided with an active layer 21 and a two-dimensional photonic crystal layer 23 which are held between upper electrodes 33 and a lower electrode 27. A current is introduced from one upper electrode 33 or the plurality of the upper electrodes 33 disposed adjacently. Therefore, the active layer 21 generates light and the light is intensified by diffraction in the two-dimensional photonic crystal layer 23, so that a stronger laser light is emitted to the outside from around the upper electrodes 33 into which a current is introduced. When the current-injected upper electrodes are sequentially switched, a laser light scan is performed in the direction of the array of the upper electrodes. Since this switching can be made electrically, a laser light scan can be achieved at a high speed without using the mechanical scanning mechanisms.

    摘要: A two-dimensional photonic crystal surface-emitting laser having a photonic crystal (20) in which a photonic crystal periodic structure (21) is located in or near an active layer (first medium) (12) which emits light when carriers are injected thereto. The photonic crystal periodic structure (21) comprises a second medium with a refractive index different from that of the active layer scattered in two-dimensional periodic array. The photonic crystal periodic structure is of a square lattice structure or a triangular lattice structure which has translation symmetry but does not have rotation symmetry. Alternatively, the phtonic crystal periodic structure is of a square lattice structure or a rectangular lattice structure which is classified into pl, pm, pg or cm according to the two-dimensional pattern classification method. It is the most desirable that the lattice structure is composed of triangular lattice points.

    摘要: Two pieces of semiconductor wafers 101 and 102 to be stacked and fused together are secured to wafer holders 201 and 202 respectively, and are then integrally held at a wafer hold unit 2. Rough position alignment is first applied to these semiconductor wafers 101 and 102 while supplying infrared light thereto from an infrared light source 30 of an infrared light system 3 for detection of a resultant lattice image at a detection unit 5. Then, fine position alignment is performed while supplying laser light from an laser light source 40 of a laser light system 4 for detection of a resultant diffraction image at the detection unit 5. Thus, in the manufacture of a semiconductor device having its crystal structure with three-dimensional periodical refractive index distribution employing precision multilayer stack methods by using a wafer fusion, a method and apparatus for manufacturing the semiconductor device is realized which is capable of achieving precise position alignment between lattice layers stacked over each other with reduced complexity in position alignment thereof.
