The XPDV412xR comprises an optimized 100 GHz waveguide-integrated photodiode, which
shows an extremely flat frequency response in both, power and phase. The on-chip integrated bias
network with an optimized RF design in particular, ensures an undisturbed frequency response
from DC to the 3 dB cut-off frequency and saves costs for internal bias-tees. The module is
especially designed for optimal RF performance; therefore the pulse response reveals virtually no
ringing. A further advantage of the waveguide structure is the unbeatable high-power behavior.
The photodetector shows a linear response up to an optical input power of 10dBm. An output
voltage swing of more than 0.5 Vpp can be achieved for short pulses without any degradation of
the pulse response. Each photodetector module is characterized in the frequency domain by using
a heterodyne technique. In the time domain, a femto-second pulse source and a 70 GHz sampling
oscilloscope are used to measure the pulse response.
