Abstract (in Japanese) (See Japanese page) 
(in English) In fiber transmission systems, to place signal regenerators within the system is effective for reducing noise and signal distortion and extending the transmission distance. In this paper, we propose an opto-electronic coherent signal regenerator for binary phase-shift keying (PSK) signals and show its effectiveness by an experiment. The features of the regenerator are: (1) It generates output signals by the use of an electro-optic Mach-Zehnder modulator after the input signals are converted to electric signals by a photo detector. Because it reduces noise on the signal by nonlinear nature of the modulator, realization of compact regenerators is expected. (2) The input PSK signals are demodulated to OOK signals by coherent detection, with which high-sensitivity signal regeneration and extension to regeneration of multi-level signals are expected. can be hoped high sensitive signal regeneration and expansion to Multi- level signals. It is noted that techniques of generating phase-locked local light waves should be established for realization of this regeneration scheme.
