Title: Fiber for light amplification and its manufacture
Inventor: OKAMURA KOJI
IPC: C03B37/012
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a fiber for light amplification which has a wide wavelength band and can improve the conversion efficiency for converting excited light into signal light, by suppressing the mode field diameter of the fiber to a small value. SOLUTION: A fiber for light amplification contains a clad 34, a first core 36 which is provided on the inside of the clad and contains Ge, a second core 38 which is provided on the inside of the first core 36 and contains Er and Al, and a third core 40 which is provided on the inside of the second core 38 and contains Ge. The second core 38 has a refractive index higher than the clad 34 has, and the first and third cores 36 and 40 have refractive indexes higher than the second core 38 has. Since the third core 40 having the highest refractive index is positioned at the center, the mode field diameter 64 of the fiber can be reduced and the conversion efficiency for converting excited light into signal light can be improved.

Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To prevent power ripples from being mixed into output by connecting a resistance land where feedback resistance is arranged to an output point in the integrated circuit of a light to electricity conversion circuit converting the output current of a photodiode into voltage. SOLUTION: The common resistance land L where resistances R1 -R3 constituting feedback resistance Rk are arranged is connected to a point B connected to an output terminal 3. In a resistance land where resistance Ro is arranged, resistance Ro decided in accordance with the transistor of the input stage of an arithmetic amplifier 1 is connected to a high potential-side.Voltage connecting the resistance land is required to satisfy a condition that it is not less then voltage on arranged resistance. Thus, there is not problem in the connection method of the resistance land. Then, the occurrence of the ripples owing to the fluctuation of power voltage is prevented in voltage connected to the resistance land, and the power rippers are prevented from being mixed in the output of the light to electricity conversion circuit.
