Abstract :
We optimize the laser power and quantum well (QW) modulator metrics (contrast ratio (CR), insertion loss (IL)) to minimize power dissipation in short distance, modulator based, optical interconnects. We correspondingly quantify the optimal CR/IL modulator requirements as a function of various bit rates and a parameter dictated by voltage swing. This ultimately yields higher aggregate I/O bandwidth for chip to chip communication in power limited chips.
