We show an evanescent waveguide coupling AlInAs/InGaAs SAGM APD using a short multimode waveguide for 40Gb/s optical transmission. Very thin avalanche and absorption layers together with a well optimized diluted waveguide allow achieving simultaneously a broad bandwidth (> 26GHz for multiplication factors up to M=7-8) and a high responsivity of Rmax = 13.4 A/W at 1.55micrometer.
