Abstract(in English) We have focused on an ultra small nanocavitiy in 2D photonic crystal (PhC) platform and realized an all-optical bistable memory on a Si based PhC operating with very low power. However, it is very difficult to achieve a long memory time for a Si based PhC owing to the accumulated heat in the cavity. To solve this problem, we developed ultra high Q AlGaAs and InGaAsP based PhC nanocavitis. Their Q factors are 690,000 and 130,000 respectively, which are highest Q factor ever reported. The memory time of A1GaAs-PhC cavity is conceptually infinity. As for the InGaAsP-PhC, the longest memory time is 150ns and minimum bias power for bistability and switching ON energy are extremely low at 40μW and 30fJ, respectively.
