Outline of Final Research Achievements

In this work, we demonstrated an optical quantization technique using red frequency chirp in a semiconductor optical amplifier. First, we investigated the performance of optical filters for slicing input signal pulse induced by red frequency chirp. And, to optimize the optical quantization performance, we evaluated the input power dependence on the performance. Lastly, we successfully achieve 10-GSamples/s, 15-level optical quantization using frequency chirp in a quantum-dot semiconductor optical amplifier. The scheme has much lower input signal power than previously reported schemes.

Academic Significance and Societal Importance of the Research Achievements

高速なアナログ信号をデジタル信号に変換する需要がデータ通信・解析などの多岐にわたる分野で急速に拡がっている.このため,光領域でアナログ・デジタル変換を行う光アナログ・デジタル変換の研究開発が盛んに行われている.本研究では,これまでにない,小型の半導体素子内で発生する周波数シフトを応用した光量子化技術によって,小型,省電力かつ高性能を実現する実証実験に取り組み,その有効性を明らかにしている.
