Title: Optical isolator, distributed feedback laser and optical integrated element
Inventor: KINOSHITA JUNICHI
IPC: H01S3/1055
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain high directivity, by comprising a waveguide having a second- or higher-order diffraction grating asymmetric in section and reflectivity different at both sides of the waveguide to a radiation mode light emitted from the waveguide. SOLUTION: The optical isolator has second- or higher-order diffraction grating 10, esp., a waveguide structure having a second-order diffraction grating 10 emits a radiation mode light to a substrate perpendicularly to the guiding direction and reverse direction, the second-order diffraction grating 10 has an asymmetric sectional shape in the traveling direction, i.e., a blaze angle land hence the radiation mode at the substrate 1 side becomes strong and weak in either the right or left traveling direction of the light wave, depending on the blaze angle. When the guided light runs from the right to the left, the radiation mode light is mostly radiated to the substrate 1 and absorbed by an absorption layer 30, not returning to the waveguide.  When running from the left to the right, the radiation mode light is mostly radiated upwards reverse to the substrate 1 and returnes by a reflection structure 20, and thus a high directivity can be obtd.

Filed: 1989-05-10
Abstract: PURPOSE:To stop the gas supply at the same oxygen concentration in oxygen deficiency regardless of burning intensity by changing the reference value to stop the gas supply to burner depending on the electric current level to a proportional solenoid valve. CONSTITUTION:The electromotive force of a thermocouple 10 which is disposed adjacent to the burner 1 to detect its poor burning condition and the reference voltage which is determined by the output signal from proportional control valve 6 and the divided voltage resistance 12, 13 are compared in a comparator 14. If the comparator circuit 11 outputs a comparison signal which indicates that the electromotive force of the thermocouple 10 is lower than the reference value, a burning control circuit 15 causes an electromagnetic safety valve 2 to close to stop the gas supply to the burner 1. That is, when the setting unit is operated to increase the power supply to the exciting coil 3a of an electromagnetic proportional valve 3 to increase the burning rate at the burner 1, the reference value becomes greater. On the other hand, when the power supply to the exciting coil 3a is decreased to decrease the burning rate at the burner 1, the reference value becomes smaller.
