    摘要： An aluminum nitride (AlN) substrate comprising an AIN sinter, an Al.sub.2 O.sub.3 layer provided on the sinter, and a glass-mixed Al.sub.2 O.sub.3 layer which is provided on the Al.sub.2 O.sub.3 layer and contains Al.sub.2 O.sub.3 and glass mixed therewith, preferably with an oxide particle-dispersed glass layer and a main glass layer provided on the glass-mixed Al.sub.2 O.sub.3 layer. The AlN substrate has heat dissipation properties closer to those of AlN itself, does not cause generation of air bubbles at the junction interface between the AlN sinter and the glass-containing layer, and has excellent surface smoothness and corrosion resistance. The very fine conductive layer, etc. may be readily and firmly formed on the substrate in a stable manner.

    摘要： A glazed AlN substrate includes: a sintered AlN body, a surface oxidized layer formed on the sintered AlN body, an Al.sub.2 O.sub.3 --SiO.sub.2 layer formed on top of the intermediate surface oxidized layer, and a glass layer formed on top of the Al.sub.2 O.sub.3 --SiO.sub.2 layer. In one embodiment, an additional SiO.sub.2 layer is interposed between the glass layer and the Al.sub.2 O.sub.3 --SiO.sub.2 layer. A method of producing the AlN substrate is also disclosed that permits firing of the glass layer at high temperatures.

    摘要： A variable focusing lens is provided that can change the focal length at a high speed. The variable focusing lens includes: a single crystal electrooptic material having inversion symmetry; a first anode formed on a first surface of the electrooptic material; a second cathode provided to have an interval to the first anode; and a first cathode and a second anode that are formed on a second surface opposed to the first surface and that are formed at positions opposed to the first anode and the second cathode. An optical axis is set so that, when light enters through a third face orthogonal to the first surface, light exists through a fourth surface opposed to the third face. A voltage applied between the first and the second pair of electrodes is changed to thereby change the focal point of light emitted from the fourth surface of the electrooptic material.

    摘要： In a wavelength swept light source using a polygon mirror in a well-known art, an oscillation wavelength roughly linearly varies in an upwardly slight convex shape with respect to time. On the other hand, in a wavelength swept light source of SS-OCT, the wavelength is required to vary so that a wavenumber (inverse of wavelength) linearly varies on a time axis. The wavelength swept light source of the well-known art has had a drawback that such wavelength variation cannot be implemented; non-linear distortion occurs in a resultant OCT image; and thereby, a point spread function cannot be kept sharp. According to the present invention, in a wavelength swept light source utilizing an electro-optic deflector including a KTN and so forth, such wavelength variation is caused that the wavenumber linearly varies with respect to a time axis by applying correction, which includes a sawtooth waveform as a main waveform and an exponential component of the sawtooth waveform, to the controlled voltage of the electro-optic deflector. The controlled voltage is controlled so that, as an oscillation wavelength to be swept is swept towards a longer wavelength side, a change rate of the oscillation wavelength is increased. With the controlled voltage, the oscillation wavelength varies more quickly as the oscillation wavelength is swept towards the longer wavelength side, and time variation in the oscillation wavelength is formed in a downwardly convex shape.
