TL;DR
This paper demonstrates a high-speed silicon photonic modulator using ferroelectric nematic liquid crystal technology, achieving 102 Gbit/s PAM-4 data transmission within the C-band at low voltage.
Contribution
It is the first to integrate ferroelectric nematic liquid crystals with silicon photonics for ultra-fast modulation at 102 Gbit/s.
Findings
Achieved 102 Gbit/s PAM-4 modulation
Operates at 3.5 V DC bias within the C-band
Uses Pockels effect in a Mach-Zehnder modulator
Abstract
We present the first demonstration of a hybrid integrated silicon and ferroelectric nematic liquid crystal modulator achieving 102~Gbit per second PAM-4 modulation. Operating within the C-band at a 3.5 V DC bias, this Pockels-based Mach-Zehnder modulator exhibits a of 0.3 Vcm.
