Title: Light function fiber and fiber amplifier
Inventor: NAKAZATO KOJI
IPC: C03C13/04
Filed: 1991-04-11
Abstract: PURPOSE:To provide photoactive fiber capable of making decrease in gains accompanied by increase in input intensity of excitation light extremely small as well as to provide a fiber amplifier making use of this photoactive fiber. CONSTITUTION:An inner core 14a is formed of photoactive glass containing Nd<3+> as an active material. An outer core 14a is formed of photoactive glass obtained by adding Yb<3+> capable of absorbing fluorescence in wavelength band of 1.05mum from the Nd<3+>. These cores 14a and 14b are equal to each other in refractive index, and have the refractive index higher than surrounding clad 12. If such photoactive fiber is applied to an optical amplifier, induced emission in wavelength band of 1.05mum of the Nd<3+> can be restricted by means of light absorption of Yb<3+>, and by reason that the Nd<3+> and the Yb<3+> do not exist in close vicinity to each other, Yb<3+> can receive energy transmission, so that the possibility of emitting the fluorescence in the vicinity of wavelength band of 1.0mum is reduced. As a result of this, efficiency of emission emitted from Nd<3+> by means of induction according to signal light in wavelength band of 1.3mum projected on the photoactive fiber can be increased.

Filed: 1985-04-15
Abstract: PURPOSE:To control exactly a displacement quantity of a piezoelectric element by detecting the displacement quantity of the piezoelectric element, feeding back this value and displacing the piezoelectric element to a prescribed position. CONSTITUTION:A signal for displacing a bimorph 10 by a prescribed quantity is outputted from a signal source 11. A driving voltage detecting circuit 18 detects a driving voltage. Also, a resistance 14 detects a driving current, and outputs it to an integration circuit 16. The circuit 16 outputs a value corresponding to a total charge which has been accumulated in the bimorph 10. A subtraction circiut 20 subtracts an output signal value of the circuit 18 from an output signal value of the circuit 16 and derives an actual displacement quantity of the bimorph 10. Subsequently, this value is fed back to a driving circuit 13 through a phase compensating circuit 22. Therefore, the displacement quantity of the bimorph 10 is controlled so as to become a prescribed value. In this way, the displacement quantity of the bimorph 10 can be controlled exactly.
