Abstract
With regard to optimum signal/noise ratio at an optical receiver output, a figure of merit for an avalanche photodiode is proposed of the form η/√κ, where n is the quantum efficiency and k is the ratio of the hole ionisation coefficient β to that of an electron, α. An optimum avalanche-region width is estimated by using the figure of merit for a silicon avalanche photodiode at a given breakdown voltage.Keywords
