APPLICATIONS

 High-speed lightwave characterization  100 Gb/s communication systems  Microwave photonics 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.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operations section for extended periods of time may affect reliability. The inherent design of this component causes it to be sensitive to electrostatic discharge (ESD). To prevent ESD-induced damage and/or degradation to equipment, take normal ESD precautions when handling this product.
