TeraXion to display 400G IQ modulators at ECOC 2015

The indium-phosphide-based, high-bandwidth, dual-polarisation IQ modulator from TeraXion can enable increased spectral efficiency and reach in next-generation, single-carrier transmission systems at speeds beyond 100Gb/s, the company claims.

“Our commercially available indium phosphide modulators are ready to meet system requirements for 100Gb/s and upcoming advanced modulation formats,” stated Ian Woods, vice president of high-speed photonic components at TeraXion.

High-speed transmission systems require high modulation performance, power efficiency and small dimensions. TeraXion’s indium phosphide device delivers on all three requirements, reaching higher bandwidths up to 40GHz while being small and offering low Vπ drive voltage down to 1.5V.

TeraXion has been sampling the 400Gb/s-ready IQ modulators since the beginning of this year and says feedback is encouraging. “Customers are actively advising us that their general performance is superior to lithium niobate modulators, particularly at higher symbol rates,” said Woods.

In collaboration with academic and industry partners, TeraXion has also demonstrated compelling single-carrier 400Gb/s system performances – an achievement only possible using an dual-polarisation IQ modulator package that exhibits a bandwidth greater than 35GHz, according to the vendor.

“Our work with these partners demonstrates the clear benefits of using high-bandwidth modulators for single-carrier 400G applications,” said Woods.

As well as packaged devices, TeraXion also offers chip-on-carriers for co-packaging with lasers, drivers or receivers.

The high-bandwidth dual-polarisation IQ modulator will be displayed from 28 – 30 September at the ECOC 2015 Conference and Exhibition in Valencia, Spain, booth #528.
