    摘要: A vertical cavity surface emitting laser includes a first semiconductor multilayer reflector, a resonator, and a second semiconductor multilayer reflector. The first semiconductor multilayer reflector is formed on a substrate and is configured by stacking a high refractive index layer having a relatively high refractive index and a low refractive index layer having a relatively low refractive index. The resonator includes an active layer formed on the first semiconductor multilayer reflector. The second semiconductor multilayer reflector is configured by stacking the high refractive index layer and the low refractive index layer. The resonator includes a pair of spacer layers disposed vertically on the active layer and a resonator extension area formed at one side of the pair of spacer layers. The resonator extension area contains a material in which an energy level with a crystal defect is higher than a general energy level without the crystal defect.

    摘要: A measuring method that includes holding a specimen to be measured on a flat-plate periodic structure, applying a linearly-polarized electromagnetic wave to the flat-plate periodic structure, detecting the electromagnetic wave scattered forward or backward by the flat-plate periodic structure, and measuring characteristics of the specimen on the basis of a phenomenon that a dip waveform appearing in a frequency characteristic of the forward-scattered electromagnetic wave or a peak waveform appearing in a frequency characteristic of the backward-scattered electromagnetic wave is changed with the presence of the specimen. The flat-plate periodic structure is a flat-plate structure in which at least two voids penetrating through the structure in a direction perpendicular to a principal surface thereof are periodically arrayed in at least one direction on the principal surface, and the electromagnetic wave is applied to the principal surface of the flat-plate periodic structure from the direction perpendicular to the principal surface.

    摘要: A wiper apparatus includes: a wiper blade driven by a first motor; and a wiper blade driven by a second motor. The motors are drive-controlled by control microcomputers, respectively. The control microcomputers are connected to each other through a communication line. While exchanging position information of the wiper blades through the communication line, the control microcomputers synchronously drive the motors on the basis of a position relationship between both of the wiper blades. When an abnormality occurs in a communication state of an in-vehicle LAN, a setting state of a wiper switch is grasped through a switch signal line directly connected to the wiper switch, and wipers are prevented from being stopped when such communication abnormality occurs.
