| Outline of Final Research Achievements |
If we realize digital processing technology of optical signals in the optical domain, we can generate high-speed and low-power consumption optical random pulse patterns. It was difficult to generate such optical pulses with conventional analogue signal processing. As these random pulse patterns have regularity that never emerges in nature, they are useful for realizing highly-sensitive optical sensing systems and optical pulse sources to evaluate optical communication systems.
In this research, I established the digital signal processing technology by utilizing combined technology of photonics and electronics. The processing technology has operating speed ranging from 100 Mbit/s to 40 Gbit/s, and can be applied to both optical sensing and communication. Although I have not achieved the highly-sensitive optical sensing system (one of original main purposes) yet, I could realize a simple format conversion circuit for the optical communication, which I originally unplanned.
