Amplitude Optical Modulators O, C & L Bands: Digital and Analogue

18 Oct 2022

Lithium niobate (LiNbO3) intensity modulators are designed for modulation frequencies larger than 30GHz.  The X-cut design of the Mach-Zehnder modulators provides an unmatched stability in a wide range of operational conditions plus zero chirp performance.  iXblue’s proprietary waveguide design offers low insertion loss with a high contrast.

Key features • low insertion loss • high bandwidth • zero chirp • low driving voltage • high second harmonic rejection

Applications include digital modulation NRZ, RZ, DPSK, duo binary modulation formats, up to 44Gb/s-NRZ, QPSK-56Gb/s and analogue modulation up to 40GHz.

Matching modulator digital driver amplifiers are DR-DG and the DR-AN family for analogue applications. The DR-DG drivers are optimised for peak-to-peak voltage, rise/fall times and jitter and the DR-AN is characterised by a low noise figure and a linear transfer function with optimised 1dB compression point.  The driver exhibits flat group delay and gain curves with reduced ripple over the bandwidth.
