Low-drive voltage LiNbO3 electro-optic modulator for 2.5 Gbit/s and beyond B-ISDN a

摘要

Abstract: We report the demonstration of a very low drive voltage (V$-$pi$/) $EQ 1.7 V) LiNbO$-3$/ electro-optic modulator suitable for 2.5 Gbit/s and 5 Gbit/s digital transmission applications. This modulator has the lowest reported voltage and length product of 3.5 V/cm and a 3 dB electrical bandwidth of DC to 2.5 GHz.!2
