2.5 dB sensitivity improvement by optimizing the driving voltage of an MZM and electrical filter bandwidth of optical duobinary transmission systems

Abstract

We numerically and experimentally demonstrated that 100% driving voltage doesn't necessarily yield optimal results in duobinary systems. Compared with conventional condition, a 2.5 dB sensitivity improvement is obtained using 3 GHz LPFs with optimum voltage. (C) 2006 Optical Society of America.
