Coherent Introduces 200G InP EML Lasers


InP electro-absorption modulated lasers are for 800G and next-gen 1.6T datacom transceivers

Coherent has introduced 200 Gbps InP electro-absorption modulated lasers (EMLs) for high-speed data centre transceivers.

Coherent's EML devices are said to be designed for high reliability and high signal integrity, enabling transceiver modules operating at data rates of 800 Gbps (with 4 lanes) and 1.6 Tbps (with 8 lanes) for the explosive growth in high-speed datacenter connectivity.

“We developed a high performance EML chip with a monolithically integrated electro-absorption modulator and laser that can be mounted in a low-cost non-hermetic package. This design provides our customers with the most advanced, robust, and cost-competitive laser devices for their 800G and next-gen 1.6T datacom transceiver designs,” said Karlheinz Gulden, SVP, Laser Components & Subsystems Business Unit.

“Our world-class and highly reliable InP technology platform is one of the very few in the industry that has been proven, with more than one hundred million lasers in the field deployed over the last decades. The new EML devices enable the 800 Gbps transceivers of today and the 1.6 Tbps transceivers of tomorrow."
