Abstract
Link performances at 2.5 Gbit/s for a packaged, InGaAsP-based, monolithically integrated Mach-Zehnder modulator and DFB laser, and a co-packaged discrete Mach-Zehnder modulator and DFB laser, are reported. Both modulators feature a switching voltage of ~2 V, and an on-chip absorber for optical power adjustment of up to 15 dB. Negative dispersion penalties at 1.55 µm for > 1000 km of NDSF are achieved with both modules.Keywords
