1.4 mA (70 mV) peak-to-peak drive of 1.25 Gb/s frequency modulated laser for WDM coherent access networks

A new laser suitable for access-systems with FM efficiency up to 7 GHz/mA and negligible amplitude modulation is presented. It enables 1.25/2.5 Gb/s operations with extremely low driving signals: 70 mVpk-pk and 250 mVpk-pk respectively.
