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： 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.

摘要： An objective of the present invention is to provide a surface emitting laser capable of selectively generating a laser oscillation in the fundamental mode and thereby emitting a single-wavelength laser light. In a surface emitting laser including an active layer and a two-dimensional photonic crystal provided on one side of the active layer, a reflector 45 or 46 is provided at least at a portion of the circumference of the two-dimensional photonic crystal. The reflector has a reflectance distribution in which the reflectance has a maximum value at a position where the amplitude envelope of the fundamental mode of an internal resonance light created within the two-dimensional photonic crystal. This design strengthens the fundamental mode while suppressing the second mode, thus enabling the laser oscillation in the fundamental mode to be selectively obtained, so that a single-wavelength laser light can be emitted.

摘要： A two-dimensional photonic crystal LED composed of a p-type semiconductor cladding layer 12, an active layer 11 of light-emitting material, and an n-type semiconductor cladding layer 13 placed between a pair of electrodes, where air holes 16 penetrating through the layers 12, 11 and 13 and arranged periodically in the layers 12, 11 and 13 are provided. At least a part of the inner wall of the air holes 16 is oxidized 17 in either one or both of the p-type semiconductor cladding layer 12 and the n-type semiconductor cladding layer 13. The holes and electrons injected from the electrodes avoid the oxidized region 17 and enter the active layer 11 apart from the air holes 16, which minimizes the recombination (surface recombination) of the holes and electrons producing heat instead of light.

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.
