Title: Optical fiber amplifier
Inventor: TAKUMA TAKEYOSHI
IPC: G02F1/35
Filed: 1992-12-25
Abstract: PURPOSE:To increase the performance of the entire amplifier by eliminating a connection loss between an Er-doped fiber and a fiber-type photosynthetic branching filter. CONSTITUTION:A photosynthetic branching filter 12 is formed integrally with an Er-doped fiber 11 at a terminal section of the Er-doped fiber 11 by fusing and extending the Er-doped fiber 11. By this method, a fusion connection between the Er-doped fiber 11 and the photosynthetic branching filter 12 is eliminated. Excited light of a light source for excitation 13 is input from the photosynthetic branching filter 12 into the Er-doped fiber 11 from the inverse direction. Signal light input into the Er-doped fiber 11 from an input port 16 through a polarization-independent type optical isolator 17, together with the excited light input from the inverse direction, is propagated through the Er-doped fiber 11 and is amplified. The amplified light is branched by the photosynthetic branching filter 12 and is taken out from an output port 15 through the optical isolator 14.

Title: Offset adjusting circuit
Inventor: NARA MASAAKI
IPC: G11B7/09
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To finish the adjustment of offset at a time even when the offset of a tracking error signal is large. SOLUTION: At the time of automatic adjustment, a difference signal is obtained from two input signals of photo diodes. When the automatic adjustment starts, a control signal is generated to be converted by a D/A converter circuit 3 into a control voltage, which is added with the DC component of the difference signal by an adder circuit 9. When the DC component of the difference signal is changed by the change of the control voltage and the output signal of the adder circuit 9 exceeds a reference value, the change of the control signal is stopped to hold the control signal in a hold circuit 2. When a smoothing signal does not exceed the reference value and the control signal becomes maximum, it is detected by a compulsive stop circuit 12 and the change in the control signal is caused to stop. At the same time, the maximum value of the control signal is held in the hold circuit 2.
