Coherent launches 200G InP EMLs for high-speed data-center transceivers

Coherent Corp of Saxonburg, PA, USA, which provides photonics technology for communications and aerospace & defense applications, has launched its 200Gbps indium phosphide (InP) electro-absorption modulated lasers (EMLs) for high-speed data-center transceivers.

The growing demand for 400G and 800G transceivers and the anticipated demand for next-generation 1.6Tbps transceivers for intra-data-center communications are rapidly driving a technology shift toward advanced EML devices that maintain transmission reach at higher bit rates. Coherent says that its EML devices are designed for high reliability and high signal integrity, enabling transceiver modules operating at data rates of 800Gbps (with 4 lanes) and 1.6Tbps (with 8 lanes) for the explosive growth in high-speed data-center 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,” says Dr Karlheinz Gulden, senior VP, 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 100 million lasers in the field deployed over the last decades. The new EML devices enable the 800Gbps transceivers of today and the 1.6Tbps transceivers of tomorrow.”

Coherent’s portfolio of InP components includes application-specific Fabry-Pérot lasers, directly modulated lasers (DMLs) and tunable lasers. It also includes photodiodes for high-speed receivers and power monitoring.

Coherent is exhibiting in booth #1 at the European Conference on Optical Communication (ECOC 2022) in Basel, Switzerland (19–21 September), showcasing the most recent additions to its portfolio of solutions for telecom and datacom optical networks, including giving live technology demonstrations.
