Abstract :
Low dark current and low multiplication noise properties for an In
0.53Ga
0.47As/InP avalanche photodiode are described. The diode is prepared with an In
0.53Ga
0.47As light absorption layer and an InP avalanche multiplication region. The lowest dark current density of

A/cm
2is obtained at 90 percent of a breakdown voltage. Multiplication noise power is proportional to the 2.7th power of the current multiplication factor. Impact ionization coefficient by holes is larger by 2-3 times than that by electrons in
