| Abstract(in English) | For an application of quantum dot photo-detection devices, we have proposed and demonstrated new high speed photodiodes using In As based quantum dots absorption layer. To compare the performances with conventional In GaAs based photodiode, low dark current, high absorption coefficient and avalanche multiplication effect were observed in the new devices. The 3dB bandwidth at low bias was expected as approximately 50GHz, and the Gain Bandwidth (GB) products in avalanche multiplication region would be 150GHz to 200GHz. |
