| 英文摘要 | PURPOSE:To obtain output light of high-speed photo pulse array by a method wherein output light supplied with potential difference to each other are added to those coming from a plurality of laser light souces. CONSTITUTION:An N-InP substrate 51 is provided with semiconductor lasers 11-14 of the same shape and dimensions, having resonance planes 21-24, 31- 34. The output light of each laser 11-14 is led out in one direction by being synthesized in the wave confluence of waveguides 41-44. The lasers 11-14 are subjected to force mode tuning by the drive part and then generate short pulses each shifted in phase by pi/2 with respect to the described frequency (f). The short pulses are modulated in gain by the on-off operations of photo modulators 35-38 with respect to respective frequencies. Each output of the photo modula- tors is synthesized in the waveguides 41-44 and can obtain photo pulse arrays having a repeated frequency 4f that is four times. The photo pulses are turned on and off by impressing voltage on each modulator from other drive parts in forward and reverse directions. For example, a photo pulse aray with a repeated frequency of 8GHz can be obtained with respect to the modulation of 2GHz. |
