| Outline of Final Research Achievements |
All-optical communication system, which does not use opto-electric conversion, is indispensable for high speed operation and low power consumption. A large number of all-optical flip-flop operation systems have been studied, but most of them are RS type. On the other hand, realization of the JK type makes it easy to simplify the transition circuit, so it is merit that the number of elements can be reduced when constructing a circuit with an optical element which is subject to integration many subjects.
In this study, we proposed that the JK flip-flop operation is possible by combining a polarization bistable VCSEL and an optical feedback system. We studied elemental technologies such as the optical feedback system and the signal processing by optical pulses having different wavelength.
