摘要
A novel top-illuminated metamorphic In0.53Ga0.47As p-i-n hotodiodes (MM-PINPD) grown on GaAs substrate by using a linearly graded InxGa1-xP (x graded from 0.51 to 1) buffer layer is reported. The dark current, optical responsivities, noise equivalent power (NEP), and operational bandwidth of the MM-PINPD with aperture diameter of 60 μm are 13 pA, 0.77/0.59 (1310/1550 nm) A/W, 6.9×10-11 W/Hz1/2, and 7.5 GHz, respectively. The performances of the MM-PINPD on GaAs are demonstrated to be better than those of a similar device made on InGaAs/InP substrate.
