Summary form only given. Speed will be the key attribute of the photoreceivers of fiber-optic communication systems with channel data rates of 40 Gbit/s or over. In this paper, we report on a 40-Gbit/s digital uni-traveling-carrier photodiode (UTC-PD) and InP HEMT digital IC. By directly connecting the UTC-PD to the IC in the chip, we can disregard impedance matching between the connection line and load resistance. This enables us to design in a higher load resistance for the UTC-PD, which increases the drivability of the UTC-PD.
