Abstract
We report a new PIN photodiode using an InAs/InAsGaAs quantum-dot absorption layer with avalanche multiplication. For this photodiode, excellent I-V curves showing avalanche multiplication and a high 3-dB cutoff frequency were achieved. Designing advanced wide bandwidth avalanche photodiodes over 40 GHz is challenging [1]. A PIN structure that has a multiplied absorption layer is advantageous for realizing a short transit time in contrast to a separated absorption and multiplication (SAM) structure. Moreover, quantum dot technologies applied for obtaining high photovoltaic efficiency in solar cells are very attractive.
