Abstract
We investigate the effect of the electric-field profile on the gain-ba ndwidth product of avalanche photodetectors with separate absorption a nd multiplication. We show that for a given multiplication layer thick ness the electric-field profile plays an important role in determining the gain-bandwidth product. The calculation results show that an incr easing triangular electric-field profile yields a larger gain-bandwidt h product than most other profiles for Si/InGaAs avalanche photodetect ors.
