| Outline of Final Research Achievements |
This study proposes a simple scheme for extending transmission distance of multivalued optical signals without resorting to high-speed analog-to-digital conversion and large-scale digital signal processing. The scheme uses an opto-electrical signal regenerator consisting of optical homodyne detection together with analog electrical signal processing and an intradyne opto-electrical signal phase conjugator in combination.
In this project, a novel method of generating optically phase-locked local oscillator light for homodyne detection is proposed and studied, and dispersion and nonlinearity compensation performance of an indradyne opto-electrical signal conjugator is demonstrated.
