摘要：

We propose to use 1.55 mu m intersubband transitions as a key mechanism for novel photonic devices such as fast photonic switches which are applicable to current optical communication systems. The calculation of carrier relaxation times shows a few picosecond switching time for 1.55 mu m intersubband transitions. The well-width dependence of intersubband transition energies in InGaAs/AlAs pseudomorphic quantum well structures has been studied to realize 1.55 mu m intersubband transitions.
