Coherent Corp, an $11 billion market cap company specializing in photonics, has announced the launch of a groundbreaking 400 Gb/s Differential Electro-absorption Modulated Laser (D-EML), marking a significant milestone in high-speed optical networking technology. This new offering is geared towards enhancing data center operations, especially as they scale to meet the demands of growing AI AI infrastructure. According to InvestingPro data, the company has shown strong revenue growth of 14.6% over the last twelve months, positioning it well in the expanding optical technology market. The 400G D-EML is designed to address the challenges in optical transceiver designs for 1.6T and the forthcoming 3.2T connectivity requirements. It builds on the company’s previously recognized 200G D-EML technology. The differential design of the new D-EML stands out by doubling the signal amplitude, which reduces power consumption and minimizes crosstalk, leading to improved Optical Modulation Amplitude (OMA) and Extinction Ratio (ER) performance.
The integrated on-chip termination network of the D-EML is another feature that optimizes electrical performance, reducing the need for extensive signal pre-conditioning and thus enhancing signal integrity. This technology is intended for use in cost-effective, non-hermetic packaging solutions. Dr. Beck Mason, Executive Vice President of Telecommunications at Coherent, highlighted the company’s dedication to innovation and technological leadership. He also acknowledged Ciena for their support with a DSP chip that facilitates the demonstration of the new laser. According to InvestingPro, 16 analysts recently revised their earnings expectations upward, and the consensus recommendation is 1.84 (Strong Buy), which suggests the market appears optimistic about the company’s technological initiatives.
The 400G D-EML will be showcased at the Optical Fiber Communication Conference and Exhibition (OFC) 2025, which will take place from April 1 to 3. The product will be available under controlled availability upon request. Meanwhile, the general availability of the 200G D-EML is projected for 2026. Coherent’s extensive portfolio of optical and semiconductor high-performance solutions will be on display at OFC 2025, where industry professionals can engage with the latest technological advancements.
