Abstract: PROBLEM TO BE SOLVED: To output a light signal where a signal waveform distortion in a semiconductor light amplifier is compensated by providing a saturable absorption body where the output light of the semiconductor light amplifier is inputted and a light-controlling means for controlling output light from the saturable absorption body. SOLUTION: A current injected into the active layer of a semiconductor saturable absorption body 2 is controlled by a light output control means 3, and the absorption rate of the medium of the light absorption body 2 is increased and is set to a current value that operates as a loss medium. In this case, an output level is large at the tip part of a pulse in the waveform distortion of a semiconductor light amplifier 1 and is eased to a lower level. Also, the pulse response of the absorption body 2 is in the form that it is eased to a high-level steady value from a low level and has characteristics opposite to those of the light amplifier 1.  Therefore, the light absorption body 2 is placed at the rear stage of the light amplifier 1 and the control means 3 is provided, thus enabling both dynamic characteristics to compensate each other and hence obtaining signal light with less waveform distortion.

Title: Bit synchronizing circuit
Inventor: ARAKAWA TADAHIRO
IPC: H03K23/66
Filed: 1987-12-29
Abstract: PURPOSE:To reduce and stabilize the jitters of a regenerated clock signal by providing a circuit which outputs the regenerated clock signal and two control circuits, and controlling the frequency division number of a variable frequency dividing circuit by a 1st control circuit at a relatively high frequency at the time of rising and at a relatively low frequency after the rising. CONSTITUTION:When an NRZ signal rises, carries 5 and 6 outputted by an up/down counter 3 are increased in frequency to attain bit synchronization fast. On the other hand, a circuit rises and a relatively small correction value + or -DELTAn0 of high stable mode is inputted from a terminal 8 and then a frequency division number switching circuit 9 increases or decreases the frequency division number (n) of the variable frequency dividing circuit 10 to a relatively small correction value n+DELTAn0 or 2-DELTAn0 every time the carry 5 or 6 is inputted. Then a reference clock signal is put in phase with the regenerated clock signal stably with small correction width. In this case, the number L of stages of the up/down counter 3 is set large to decrease the frequency of the carries 5 and 6 outputted by the counter 3, thereby reducing the jitters of the regenerated clock signal.
