    摘要: [Object] A self-written branched optical waveguide is formed.[Solving Means] A laser beam 2 from a laser source (not shown) is focused with a lens 3 onto the face of incidence 10 of an optical fiber 1. The laser beam of an LP11 mode was emitted from the face of emergence 11, and “bimodal” light intensity peaks were arranged in the horizontal direction (1.A). A slide glass 4 coated with a photocurable resin gel 5 was placed horizontally (1.B). A single linear cured material 61 was formed as the LP11-mode laser beam was emitted from the face of emergence 11 of the optical fiber 1 (1.C). A branch portion 62 was then formed at a distance L from the face of emergence 11 of the optical fiber 1, which was followed by the growth of two cylindrical cured materials 63a and 63b. The two cylindrical cured materials 63a and 63b were linear branches, and formed an angle of about four degrees. An optical waveguide 60 thus formed was composed of cured materials 61, 62, 63a, and 63b (1.D).

    摘要: An A/D converter comprises capacitors C1, C2, C3, C4, and C5 coupled via a plurality of switches to a differential input/differential output amplifier 1. The capacitor C5 determines a gain of the amplifier 1. A reset level is stored in the capacitor C1, and a signal level is stored in the capacitor C2. One terminal of the capacitor C1 and one terminal of the capacitor C2 are coupled to the respective differential inputs, and the other terminals of the capacitors C1, C2 are coupled to each other, whereby the amplifier 1 generates a difference signal between the reset level and the signal level. The cyclic A/D conversion of this difference signal is performed by switching the capacitors C1, C2, C3, and C4 coupled via a plurality of switches to the differential-input/differential-output amplifier 1, thereby obtaining an A/D conversion value with reduced random noise.

    摘要: An A/D conversion array for an image sensor, in which the number of amplifiers and capacitors are decreased, compared with the conventional cyclic type, and a function to cancel the noise generated in the pixel section of the image sensor is provided, so that the area and power consumption are decreased. After input signal Vin is supplied to C1 and held, a reset level is applied to Vin, whereby the signal is amplified by the ratio of C1 and C2 (C1/C2). An output is held in C1, and the output is A/D-converted by a comparator so that a control signal is generated by the conversion output and a switch is turned ON. The digital signal is converted into an analog signal, and the analog signal is subtracted from the signal held in C1. This signal is amplified and is subjected to A/D conversion again, and the same operation is repeated.
