Inventor: YAMAGUCHI MASAYUKI
IPC: G02F1/015
Filed: 1992-09-18
Abstract: PURPOSE:To suppress loss at the time of injection of tuning current while ensuring refractive index substantially equal to a conventional one by providing a tuning layer having multiple quantum well structure thereby distributing electrons contributive to variation of refractive index over the entire tuning layer and locarizing holes causing absorption loss within a narrow well layer. CONSTITUTION:A tuning layer 3 has total thickness of 300nm and includes an InGaAsP barrier layer 140 and triple InGaAsP well layers 130. The well layers 130 are separated from each other by means of the barrier layer 140 of 10nm thick and positioned substantially in the center of the tuning layer 5. The tuning layer has effective band gap of 0.875eV which is higher by 75meV than the energy of laser beam having oscillation wavelength of 1.55mum. When an element of 600mum long is fabricated, laser oscillation takes place at an oscillation threshold current of 25mA and maximum optical output of 15mW can be obtained.

Title: Wavelength converting element
Inventor: UENISHI NAOTA
IPC: G02F1/361
Filed: 1989-09-26
Abstract: PURPOSE:To convert a fundamental wave into a secondary higher harmonic by setting the specific refractive index difference between a core and a clad to the fundamental wave above a specific value. CONSTITUTION:The wavelength converting element A uses single crystal of 3,5-dimethyl-1-(4-nitrophenyl)pyrazole(PRA) for its core 1 and SF4 glass for its clad 2. The specific refractive index difference (n(omega)-N(omega))/n(omega) of this element to the fundamental wave is >= 0.15. Here, n(omega) is the refractive index of the core 1 to the fundamental wave and N(omega) is the refractive index of the clad 2 to the fundamental wave. Consequently, even when the diameter of the core 1 is decreased, the power of the fundamental wave confined to the core 1 can be held constant. Consequently, the power density Pomega/a (Pomega is the power of the fundamental wave and (a) is the diameter of the core 1) in the core 1 increases and the fundamental wave can be converted into the secondary higher harmonic with high efficiency.

Title: Ac constant current amplifier
Inventor: MUKOGASA YUKIO
IPC: H03F3/68
Filed: 1986-10-22
Abstract: PURPOSE:To make the output current constant independently of the phase of the output current by converting the output current into a voltage, rectifying the voltage, controlling the feedback resistor to the input side by a potential difference between a reference voltage and the rectified voltage based on the output current so as to adjust the amplification factor of the titled amplifier. CONSTITUTION:The output current i0 outputted from an output terminal 2 is converted into a voltage through a resistor R3 and smoothed by a capacitor 11 and made into a DC. The voltage is amplified by an operational amplifier 12. The output voltage of the operational amplifier 12 and the reference voltage adjusted/set in advance by a variable resistor 16 are given to an operational amplifier 13, where the difference between both voltages is amplified and the result is impressed to a light emitting diode 19. In this case, said potential difference being the output voltage of the operational amplifier 13 is increased corresponding to the increase in the output current i0. Then the input current to a photocoupler 18 is also increased and the resistance of a photoelectric transducer 20 is decreased accordingly. Thus, the resulting resistance of the feedback loop is decreased, the amplification factor of the amplifier is adjusted and the output current i0 being constant is obtained at the output terminal 2.
