Integrated Coherent Transmitter (ICT) up to 32 Gbaud Symbol Rates

CT6100AAA

Integrated Coherent Transmitter (ICT) up to 32 Gbaud Symbol Rates

The Lumentum ICT is a C-band (196.1 to 191.15 GHz) flex-tuneable transmitter gold box, developed as an enabling source for analog and digital module integration, or line-card developments. 

The transmitter comprises full-band narrow linewidth DSDBR tunable laser, and dual-Cartesian Mach-Zehnder modulator, fabricated on indium phosphide (InP), and encapsulated with polarization multiplexer and coupling optics inside a fully hermetic package.

A single InP laser source with integrated SOA is used to derive both the local oscillator and Mach-Zehnder transmit local oscillator (LO) power.

Monolithically integrated SOAs are integrated on input and output arms of the modulator, enabling power to be balanced on each input polarization, and overall transmit power to be adjusted.

Output shuttering is enabled via an independent output VOA. This permits the LO to be maintained regardless, as required for certain application configurations.
