Graphical Approach for Evaluating Performance Limitations in Externally Modulated Analog Photonic Links
ABSTRACT We present a novel graphical approach for evaluating the performance of analog photonic links employing an external intensity modulator biased at quadrature. A single graph is sufficient to grasp the engineering tradeoffs among noise figure, third-order spurious-free dynamic range, and RF gain for various values of half-wave voltage and dc photocurrent.

ABSTRACT: As the current handling - bandwidth product of a single photodiode comprised of lattice matched In0.53Ga0.47As/InP material reaches a practical limit, we explore new lattice mismatched material system of In0.72Ga0.28As/InAsP/InP as a path-forward technology to increase this key parameter.Photonics Conference (IPC), 2012 IEEE; 01/2012
