Abstract :
Temperature-dependent measurements were per formed on planar separate absorption, grading, charge, and multiplication (SAGCM) avalanche photodiodes (APD´s). The bandwidth versus gain dependence, gain, and breakdown voltage are strongly correlated with the temperature. The gain-bandwidth product and minimum gain for useful bandwidth both increase with decreasing temperature or decreasing breakdown voltage. This is the first report of non-room-temperature performance of these devices.<>
