Title: Light emitting device having integrated component including at least one laser section and at least one modulation section
Inventor: PHILIPPE BROSSON
IPC: H01S5/026
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To reduce adrabatre frequency drift and vibration of outputted light pulses, by correcting the refractive index of a laser section forming a laser wave, and servo-controlling the phase of the wave supplied to a modulator section. SOLUTION: An ILM element has a first section supplying laser wave and a second section 2 for malediction. Servo control of phase is attained by correction the refractive index of a laser section by injecting a correction current. The first section is composed of only an oscillator section 1. A DC current supply source SC1 injects a current I1 in the lateral direction, penetrating the laser section 1. A modulation means applies a voltage V1 which is ON/OFF modulated by applying a backward bias to a terminal of a modulator section 2. A means measuring the modulation amplitude of the voltage V1 between terminals of the oscillator section is provided with a high frequency amplifier 5 and an AC/DC converter 6. The high frequency amplifier 5 receives the voltage V1 between terminals of the oscillator section 1 and delivers AC component of the voltage.

IPC: G02F1/313
Filed: 1990-11-19
Abstract: PURPOSE:To realize monolithic integration with the other active element by disposing an electrode having the inversion DELTAB structure of an N stage at an integration part, forming a first and a second electrode by conducting one upstream side and the other downstream side of an optical waveguide and one downstream side and the other upstream side and changing the driving condition of both of them.

When such an state is maintained and the reversed bias voltage of -16V is impressed on the second electrodes 14a, 14b and 14c, the light of the TE mode is emitted from an emitting end 12b and the light of the TM mode is emitted from the emitting end 11b. Then, both modes are separated and they function as a light mode splitter. Next, by changing the driving condition to a state that a current value is 33mA and a reversed voltage value is -18V from a state that the current value is 15mA and the reversed voltage value is -16V, the optical functional element acts as a polarized wave switch.

Abstract: PROBLEM TO BE SOLVED: To detect a toxic gas such as carbon monoxide by positioning an ion conductive solid electrolytic membrane between detection and count electrodes, and connecting the detection electrode for generating an electrical signal to a measurement means with a conductive hydrophobic top membrane. SOLUTION: In a sensor 10, an ion conductor solid electrolyte membrane 40 is positioned between a detection electrode 50 and a count electrode 60 so that the membrane 40 touches both the electrodes. Then, when CO is introduced into the detection electrode 50, protons and electrons are generated, the protons of a hydrogen ion pass through the solid electrolyte membrane 40 and moves to the count electrode 60.

Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To simplify radiation shield structure of a storage device and reduce construction cost, by storing radioactive matter in a vessel containing spent fuel and the like in a vertical hole pit and placing an upper shield in the upper pit. SOLUTION: In a storage equipment concrete body 23, air-intake paths 25 with a square cross section are formed, and in between the air-intake paths 25 a plurality of vertical hole pits 29 with a round cross section are formed. At the bottom of the pit 29, a lower shield 31 is provided and a steel vessel 50 is put on it and an upper shield 60 is fixed during storage. During storage of a steel vessel, heat generated by the spent fuel heats the surrounding air and air flows up at high temperature through the upper shield 60 and an exhaust lid 33 in the pit 29 and is exhausted. Due to the upward flow off air in the pit 29, draft is caused, which sucks in external air through the intake and into the intake path 25, and so proper cooling is obtained. The upper shield 60 suppresses neutron streaming from the steel vessel 50 and ensures the radiation level lower than the allowable value.
