摘要：

In this letter, we report on the first all-optical switching operation of intersubband absorption at an optical communication wavelength (similar to1.55 mum). The 1.55-mum intersubband absorption was achieved by InGaAs-AlAs-AlAsSb coupled quantum wells. A switching operation on an ultrafast signal (equivalent to 1 THz) was successfully demonstrated with a control pulse energy as low as 27 pJ.
