Insights
Coherent's new 400mW lasers provide technical leadership in a growing market, with planned 5x production expansion supporting future growth.
Coherent's new 400 mW continuous-wave lasers represent a significant technical achievement with performance metrics that position the company advantageously in the high-growth silicon photonics and co-packaged optics markets. The stable output power above 400 mW at 55°C with spectral linewidths below 200 kHz and relative intensity noise below -145 dB/Hz demonstrates engineering excellence in a space where few competitors can match these specifications.
The technical significance lies in the lasers' ability to overcome power and thermal challenges that have traditionally limited optical interconnect performance. Built on Coherent's Buried-Heterostructure Distributed-Feedback (BH DFB) platform, these devices offer the precision and stability needed for next-generation data center architectures where conventional electrical interconnects are reaching physical limitations.
Strategically, this announcement highlights two key developments: first, Coherent's continued innovation in InP-based photonics, and second, their planned 5x increase in production capacity with the upcoming 6-inch InP fab in Sherman, Texas. This capacity expansion is particularly noteworthy as it addresses potential supply constraints in meeting the growing market demand for advanced photonic components in AI, cloud computing, and high-performance networking applications.
The engineering sampling phase now with projected volume production in Q3 2026 provides a clear commercialization timeline. This gives the company runway to refine the technology while allowing customers time to design these components into their next-generation systems, creating potential for design wins that could translate to multi-year revenue streams as these platforms deploy at scale.
