摘要： An optical attenuator includes a first reflection portion reflecting a light incoming from an optical input portion in a direction different from incoming axis, a second reflection portion reflecting the light from the first reflection portion, an optical output portion outputting the light that is reflected by the first reflection portion after being reflected by the second reflection portion, and an optical-intensity-attenuation filter that is arranged on an optical path between the first reflection portion and the second reflection portion, optical transmittance being shifted in stages according to a position thereof. The first reflection portion is capable of turning to shift an incoming position at the optical-intensity-attenuation filter.

摘要： In the case the die cut label sheet is mounted, by detection of threshold voltage of output signal of the photo sensor, each label provisionally adhered to a front surface of the die cut label sheet is fed to a print start position. In the case the unfixed-length roll sheet is mounted, if the feeding speed is less than 40 mm/sec, by detection of threshold voltage of output signal of the photo sensor, the feeding state of unfixed-length roll sheet is judged, or if the feeding speed is not less than 40 mm/sec, on the basis of voltage change for the predetermined potential difference portion of output signal of the photo sensor, the feeding state of unfixed-length roll sheet is judged.

摘要： An intrinsic GaAs waveguide layer is formed on a p-type AlGaAs cladding layer, a quantum dot active layer is formed further thereon. An n-type AlGaAs cladding layer is formed on the center portion of the quantum dot active layer. Thus-configured semiconductor laser is allowed to successfully suppress the area of the p-n junction plane to a small level, and to obtain a high level of reliability, because there is no need of processing the center portion of the quantum dot active layer, contributive to laser oscillation.

摘要： An optical waveguide propagates a laser beam. Main diffraction grating and sub-diffraction grating couple light propagating in the optical waveguide. The main diffraction grating and the sub-diffraction grating couple the light in such a manner that propagation in a second order transverse mode of the light propagating in the optical waveguide when both the main diffraction grating and the sub-diffraction grating are disposed, is suppressed more than propagation in the second order transverse mode of the light propagating in the optical waveguide when only the main diffraction grating is disposed.
