V. Hurm et al., 40 GBIT S 1.55 MU-M PIN-HEMT PHOTORECEIVER MONOLITHICALLY INTEGRATED ON 3IN GAAS SUBSTRATE/, Electronics Letters, 34(21), 1998, pp. 2060-2062
A 36.5GHz bandwidth, 1.55 mu m wavelength pin-HEMT photoreceiver with
a distributed amplifier has been monolithically integrated on a 3in Ga
As substrate using a 0.15 mu m gate-length pseudomorphic HEMT process.
The pin photodiode has a responsivity of 0.34A/W. Clearly-opened eye
diagrams for a 40Gbit/s optical data stream have been demonstrated.
