A semiconductor laser 2 comprises an active layer 2A made of InGaAsP, which is formed between clad layers comprising InP, and electrodes 2B and 2C. Positive current pulses (a) from a current pulse generator 4 are applied to the QW absorber 1 through the semiconductor laser 2 and a wave-height controlling circuit 3. At this time, positive current pulses (c) having the same phase as the current pulses (a) are applied to the QW absorber 1. Meanwhile, light pulses (e), which are emitted from the semiconductor laser 2, are inputted to the QW part 1A of the QW absorber 1. The transmitted light pulses (e) are shaped and utilized as output light. Thus the waveform shaping of the light pulses can be carried out by using the external circuit.

Inventor: SATO HITOSHI
IPC: H03M1/82
Filed: 1987-05-26
Abstract: PURPOSE:To perform D/A conversion including DC with a high precision without using an analog device by converting a digital input signal to a code string having its 1/n time period to equalize the number of times of transition to the + direction and that to the - direction. CONSTITUTION:A digital input signal Din subjected to pulse density modulation into a ternary code string of '0' and + or -1, a clock fs, and nfs which is n-number of times as high as the clock fs are inputted to a code converting part 1. Whichever value the input signal Din has, it certainly includes one or more + and -signals and the '0' signal certainly exists between + and - signals. Therefore, the number of times of transition to the + direction and that to the -direction are equalized. Consequently, the gain deviation of a D/A converter does not occur even if the transition characteristic (rise time) to the positive voltage and the transition characteristic (fall time) to the negative voltage are different from each other in the output characteristic of a D/A converting part 2. Further, signals from negative to positive including DC are converted.
