The performance of back-illuminated avalanche photodiodes with separate absorption and multiplication regions is presented. Devices with an active area of 225 μ m2 show a maximum multiplication gain of 41 200. The calculation of the noise equivalent power yields a minimum value of 3.3× 10-14 W Hz-12 at a gain of 3000, increasing to 2.0× 10-13 W Hz-12 at a gain of 41 200. The broadening of the response edge has been analyzed as a function of bias.
