摘要： A sensor utilizing an evanescent wave and comprising a light source for emitting a light beam and a measuring chip formed into the shape of a well. The measuring chip has a dielectric block and a thin film layer formed on one surface of the dielectric block. The sensor also includes an optical system for making the light beam enter the dielectric block at angles of incidence so that a total internal reflection condition is satisfied at an interface between the dielectric block and the thin film layer. The sensor further includes a sample supply-discharge unit which is detachably installed within the measuring chip. The sample supply-discharge unit is used for continuously supplying the sample onto the surface of the thin film layer and continuously discharging the supplied sample from the surface of the thin film layer.

摘要： A near-field light-emitting element includes a transparent medium having a plane of incidence into which a laser beam enters, and a light-condensing plane on which the laser beam having entered the plane of incidence is concentrated, and a metal body provided on the light-condensing plane of the transparent medium having a first surface contacting the light-condensing plane, a second surface opposing the first surface, and an aperture which is formed to penetrate through the first and second surfaces at a position where the laser beam is concentrated and which emits a near-field light obtained from the laser beam. The metal body is arranged apart from a center of the aperture by a predetermined distance to connect together the first and second surfaces, and has a plasmon reflection plane that reflects toward the aperture a surface plasmon excited on the first and second surfaces by the laser beam concentrated at the aperture.

摘要： As shown in FIG. 1A, a first resist film 2 comprising organic high molecules and a second resist film 3 comprising a photosensitive material are sequentially applied to a substrate 1 by the spin coat method or the spray method for forming a two-layer resist. Then, a mask 4 with which a metallic fine opening pattern 6 is formed on a mask substrate 5 comprising a dielectric, such as glass, is tightly contacted with the two-layer resist. Then, light is projected onto the back of the mask substrate to carry out exposure with near field light 7 which is effused from the opening portions of the mask 4 where no metal is formed. Then, a pattern is formed by processing the second resist layer 3 for development with a developing solution. Thereafter, with the pattern in the second resist layer 3 being used as a mask, the first resist layer 2 is dry-etched with O2 plasma to form a fine pattern having a high aspect ratio, and with the pattern in the two-layer resist, the substrate is worked by etching, vapor deposition, or the like, before the two-layer resist is peeled off.

摘要： A surface plasmon sensor comprises a prism, a metal film, which is formed on one surface of the prism and is brought into contact with a sample, and a light source for producing a light beam. An optical system causes the light beam to pass through the prism and to impinge upon an interface between the prism and the metal film such that various different angles of incidence may be obtained with respect to the interface. A photodetector detects an intensity of the light beam, which has been totally reflected from the interface, with respect to each of the various different angles of incidence. An electrode stands facing the metal film with a liquid sample intervening therebetween, and a DC voltage is applied across the electrode and the metal film. A substance contained in the liquid sample is thus analyzed quickly and with a high sensitivity.

摘要： An optical wavelength converting apparatus comprises a semiconductor laser, which is capable of oscillating in a multiple longitudinal mode, and an external resonator for resonating a laser beam, which has been radiated out of the semiconductor laser and which serves as a fundamental wave. An optical wavelength converting device is located in an optical path of the fundamental wave, which has been resonated by the external resonator. A device feeds part of the fundamental wave, which has been resonated by the external resonator, back to the semiconductor laser. A wavelength-converted wave in a single longitudinal mode is thereby obtained, which wave has a high intensity and is stable.

摘要： There is disclosed an optical frequency converter of a bulk resonator structure comprising a ring resonator or V-shaped resonator made of a nonlinear optical crystal. The converter is equipped with a means for returning a laser light emitted by a semiconductor laser resonating inside the resonator to the semiconductor laser. The ring resonator or V-shaped resonator is made small in size and compact. The converter is insusceptible to vibration and needs no adjustment. Returning laser light is produced at less locations. The loss of the output light inside the resonator is reduced. The second harmonic is generated at a high efficiency. Multiple reflection is produced inside the resonator to further enhance the efficiency of the generation of the second harmonic of the laser radiation. Also, the phase of the radiation can be made uniform. The optical density can be increased.

摘要： A sensor is an optical resonator constituted by: a first reflecting body that exhibits semi transmissivity/semi reflectivity; a transparent body; and a second reflecting body that exhibits one of reflectivity and semi transmissivity/semi reflectivity, provided in this order from the light incident side. The sensor is configured such that the absorption peak of the measuring light beam by resonance in the optical resonator matches the absorption peak of the measuring light beam by local plasmon resonance generated at the surface and/or within the optical resonator. The sensor has absorption properties such that light of specific wavelengths are absorbed depending the mean complex refractive indices of the first and second reflecting bodies and the thickness of the transparent body. An emitted light beam is output from the first reflecting body. The physical properties of the emitted light beam that change according to the absorption properties are detected.
