Coherent Launches Innovative High-Efficiency Lasers
Coherent Corp. (NYSE: COHR), a global leader in materials, networking, and lasers, has announced the launch of new high-efficiency continuous wave (CW) distributed feedback (DFB) lasers. Specifically designed for silicon photonics transceiver modules, this new laser family represents a significant advancement in indium phosphide (InP) laser technology.
Revolutionizing Data Transmission Technology
Operating in the O-band (1310 nm region), the Coherent CW InP lasers vastly improve the capabilities of silicon photonics modulators used in high-speed 800G and 1.6T optical transceivers. These transceivers are at the forefront of data transmission technology, essential for meeting the growing bandwidth demands driven by the surge in machine learning networks designed for AI-focused data centers.
Enhancing Power Efficiency
With a proprietary low series-resistance design, the Coherent CW lasers achieve about 15% greater power efficiency compared to the current industry standards. This achievement is crucial for addressing the increasing demand for reduced power consumption in silicon photonics transceivers, providing clients with enhanced operational efficiency.
Market Response and Future Plans
Dr. Kou-Wei Wang, Vice President of InP Directly Modulated Lasers & Photodiodes, expressed excitement regarding the new family of CW lasers, stating, “Our innovation is generating significant interest among industry leaders. By cutting power usage, we tackle one of the most critical challenges faced by our clients. With plans for a state-of-the-art 6-inch InP fabrication facility in the future, we anticipate increasing production capacity to five times our current output, addressing the complexities associated with InP material production.”
Introducing a New Standard in Laser Technology
The first release in this advanced laser family is a 70 mW 1310 nm laser designed for uncooled, non-hermetic operation, capable of functioning at an impressive junction temperature of up to 85°C. Commercial shipments of this innovative laser will start soon. Coherent plans to introduce a higher-power laser for cooled operations and additional lasers catering to the CWDM grid in the following year.
Durability and Reliability
Beyond efficiency, these lasers are built for robustness, delivering remarkable reliability due to the removal of aluminum in the active quantum-well region. This enhancement supports the overall performance stability of the lasers under various operational conditions.
