摘要： A multi-beam semiconductor laser apparatus includes three or more stripe semiconductor laser emission units which are arranged on a substrate, isolation grooves which separate the semiconductor laser emission units from each other, and pad electrodes which are disposed on outer sides of the outermost semiconductor laser emission units. The isolation grooves are formed between the pad electrodes and the semiconductor laser emission units adjacent to the pad electrodes and between adjacent semiconductor laser emission units. A distance between two isolation grooves formed on outer sides of the outermost semiconductor laser light emission units is smaller than a distance between two isolation grooves formed on both sides of inner ones of the semiconductor laser light emission units.

摘要： A two-dimensional photonic crystal surface emitting laser light source according to the present invention includes a two-dimensional photonic crystal made of a plate-shaped body material provided with a periodic arrangement of identically-shaped holes 242A and an active layer provided on one side of the two-dimensional photonic crystal. The hole 242A is not located on a first half-line 251 extending from the gravity center G1 of the hole in a direction within the plane of the two-dimensional photonic crystal, while the hole 242A is located at least on a portion of a second half-line 252 extending from the gravity center G1 in the direction opposite to the first half-line 251. Injecting electric charges into the active layer generates light, which creates an electric field that encircles the gravity center G1 within the two-dimensional photonic crystal. For a given point on the second half-line 252 at which the hole 242A is located, there is no hole at a point that is symmetrical to the aforementioned point with respect to the gravity center G1, so that there is a difference in the refractive index between the two points. Thus, the electric field vectors at the two points are prevented from canceling each other due to destructive interference, so that the resultant laser light is stronger than conventional examples.

摘要： An objective of the present invention is to provide a laser capable of producing a radially polarized laser beam with an annular cross section. A laser oscillator 60 including an active layer 53 and two-dimensional photonic crystal 55 with circular holes 552 arranged in a square lattice pattern is provided between two electrodes 571 and 572. A first polarization control layer 581, which functions as a half-wave plate, and a second polarization control layer 582, which functions as a half-wave plate with a fast axis 592 extending at an angle of 45° to that of the first polarization control layer 581, are located on the laser oscillator 60. When a voltage is applied between the electrodes, a circumferentially polarized annular laser beam is emitted from the laser oscillator 60. When passing through the first polarization control layer 581 and the second polarization control layer 582, the laser beam is converted to a radially polarized beam. The resultant laser beam can be converged by a focusing lens to achieve a diameter smaller than the diffraction limit. Such a narrow beam is suitable for an optical pickup or many other devices.

摘要： The present invention intends to provide a surface-emitting laser light source using a two-dimensional photonic crystal in which the efficiency of extracting light in a direction perpendicular to the surface is high. In a laser light source provided with a two-dimensional photonic crystal layer created from a plate-shaped matrix body in which a large number of holes are periodically arranged and an active layer arranged on one side of the two-dimensional photonic crystal layer, the holes are created to be columnar with a predetermined cross-sectional shape such as a circular shape, and the main axis of each of the columnar holes is tilted to a surface of the matrix body. When provided with this two-dimensional photonic crystal layer, the surface-emitting laser source using a two-dimensional photonic crystal has a Q⊥ value (i.e. a Q value in a direction perpendicular to the surface) of several thousands, which is suitable for an oscillation of laser light, and the efficiency of extracting light is high in the direction perpendicular to the surface.

摘要： In a metallic structure including a metallic nano-chain with plasmon resonance absorption, a metallic nanoparticle forming the metallic nano-chain is formed in a circular, triangle, or rhomboid shape. The wavelength selectivity can be increased also by forming a closed region by mutually linking all of metallic nanoparticles that are mutually linked with bottlenecks. In a photodetector, a photodetection unit including a current detection probe, a nano-chain unit, and a current detection probe is arranged on a substrate. The nano-chain unit is a metallic structure with plasmon resonance absorption, where metallic nanoparticles are mutually linked with bottlenecks. Each current detection probe has a corner whose tip is formed with a predetermined angle, and this corner is arranged to face the tip of the nano-chain unit, i.e., a corner of the metallic nanoparticle. Photodetection with high wavelength selectivity is performed based on a change in the initial voltage of the current-voltage characteristic.
