Low loss, low chirp, low voltage, polarization independent 40 Gb/s bulk electro-absorption modulator module

A 40 GHz electro-absorption modulator module is presented with record unamplified loss (3.6 dB fibre-to-fibre), extremely low PDL (/spl les/0.3 dB over 15 dB extinction) and low absolute chirp (//spl alpha// <0.6 over the full dynamic range) using a highly manufacturable design.
