Abstract :
Summary form only given. The fabrication of a delta-doped SAGM-APD is reported. The multiplication region is only 0.3 μm thick. A gain-bandwidth product of 75 GHz has been achieved. Using a top-surface reflector, quantum efficiencies of over 70% have been obtained even though the absorption layer is only 1.1 μm thick
