II-VI Unveils 100 Gbps InP Directly Modulated Lasers


DMLs for data centres achieve high modulation speed and signal quality at high output power and low power consumption

II‐VI, a maker of semiconductor lasers for optical communications, has announced 100 Gbps InP directly modulated lasers (DMLs) for high-speed data centre transceivers.

The growing demand for 400 and 800 gigabit Ethernet (GbE) transceivers is driving substantial investments in technology advancements of DMLs due to their lower cost and lower power consumption compared to electro-absorption modulated lasers (EMLs) currently used in these high-speed transceivers.

II-VI’s 100 Gbps DMLs are differentiated by their ability to achieve high modulation speed and signal quality at high output power and low power consumption. As a result, II-VI says DMLs are preferred over EMLs in 400 GbE and 800 GbE transceivers that use 100 Gbps optical lanes.

“The technology embedded in these directly modulated lasers is so advanced that our early results were published in the journal Nature Photonics in January of 2021,” said Charlie Roxlo, VP, InP Devices Business Unit. “This breakthrough performance was achieved thanks to multiyear R&D investments and deep expertise across a broad internal multidisciplinary team of semiconductor laser physicists, high-speed RF analogue integrated circuit designers, and transceiver experts.”

II-VI’s new DMLs are built on its InP technology platform — 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 low power consumption of II-VI’s DMLs and their design for non-hermetic packaging are designed for today’s pluggable form factors and tomorrow’s co-packaged solutions.

II-VI will show its portfolio of optical communications products virtually at OFC 2021, June 6-11, 2021.
