Thanks to velocity-phase matching of the electrical signal and the optical beam, electro-optic polymers have inherently high performance, and, crucially, the potential for this to increase even further in later- generation products. Technology with this performance headroom is essential to support the continual upgrading that the internet and optical networks need. Conversely, competing technologies – both those that are incumbent and those competing for new business – may not work well beyond the maturation of the current generation of technology.
One way to visualise this performance potential is to consider the same baseline of 3 dB optical bandwidth in each modulator. Over the past 10 years, semiconductor modulators have generally been achieving around 20-30 GHz, but recent enhancements to both silicon and indium phosphide designs have raised their performance to 40- 50 GHz, occasionally approaching 60 GHz. In general,
to achieve 100G (or 100 Gbaud NRZ) and 200G (or 100 Gbaud PAM4) encoding, a 70 GHz 3 dB optical bandwidth is required.
Today, many datacentre operators are seeking technologies that can achieve 200G per lane. Since polymer modulators can reach 70 GHz, and even 150 GHz – about double current lane rates – they could pave the way for 1.6T with 4 lanes at 400G. Moreover, when enhanced with plasmonic designs, modulator devices using Lightwave Logic’s electro-optic polymer material have exhibited 3 dB bandwidths exceeding 250 GHz.
