摘要： [Object] To provide an estimating apparatus and an estimating method capable of estimating process of therapy using a laser the catheter 300 accurately in real time. [Solving Means] A photodynamic therapy apparatus 1 as an estimating apparatus is an apparatus for irradiating a tissue having absorbed photo-sensitive pharmaceutical, the photo-sensitive pharmaceutical absorbing an excitation light and emitting fluorescence, with the excitation light emitted from a tip portion of a laser the catheter 300, including a connector 210, a light source 110, and a light detection unit 130. The laser the catheter 300 is capable of being attached/detached to/from the connector 210. The light source 110 outputs the excitation light to the laser the catheter 300 via the connector 210. The light detection unit 130 detects intensity or a spectrum of the fluorescence, the fluorescence being entered from the laser the catheter 300 via the connector 210, to estimate whether the tissue has changed because of reaction between the excitation light emitted from the tip portion of the laser the catheter 300 and the photo-sensitive pharmaceutical absorbed in the tissue.

摘要： A plurality of first electrodes are disposed on one of opposite surfaces of a nonlinear optical material substrate which is divided into single domains. Each of the first electrodes is made of an electric conductor having a width which is equal to or smaller than half the width of a designed local inverted-polarization domain. A second electrode is positioned on the other of the opposite surfaces in confronting relation to the first electrodes. A voltage is applied between the first and second electrodes thereby to produce local inverted-polarization domains in the nonlinear optical material substrate.

摘要： An optical communications apparatus and method of using same in which optical coupling between an optical medium and a light emitter and a light receptor is achieved without any optical system therebetween. A minor axis of light transmission pattern on an end face of the optical fiber corresponds to the radial direction of the end face while a center C of the light emitter is displaced off from a center axis O, thereby providing improved optical coupling efficiencies.

摘要： A GaN compound semiconductor laser includes an AlGaN buried layer which buries opposite sides of a ridge stripe portion formed on a p-type AlGaN cladding layer. The AlGaN buried layer is made by first patterning an upper part of the p-type AlGaN cladding layer and a p-type GaN contact layer into a ridge stripe configuration by using a SiO2 film as an etching mask, then growing the AlGaN buried layer non-selectively on the entire substrate surface to bury both sides of the ridge stripe portion under the existence of the SiO2 film on the ridge stripe portion, and thereafter selectively removing the AlGaN buried layer from above the ridge stripe portion by etching using the SiO2 film as an etching stop layer. Thus, the GaN compound semiconductor laser is stabilized in the transverse mode, intensified in output power, and improved in lifetime.
