Coherent Unveils Cutting-Edge Photodiodes for Transceivers
Introduction to Coherent's High-Speed Photodiodes
Coherent Corp., a prominent name in high-performance optical networking solutions, has made a significant announcement regarding its latest innovation. The company has launched a new line of high-speed indium phosphide (InP) photodiodes, engineered specifically for advanced communication technologies.
Features of the New Photodiodes
These photodiodes cater to the forthcoming generation of transceivers, specifically the 800G and 1.6T types which utilize 200 Gb/s PAM4 optical lanes. Designed with both singlet and 1x4 array configurations in mind, they include integrated lenses that ensure efficient optical coupling. This versatility allows for seamless compatibility with leading 4-channel and 8-channel transimpedance amplifiers (TIA).
Optical Performance
These devices boast an extensive optical response range from 900 nm to 1650 nm, exhibiting superior responsivity at 1310 nm. With a remarkable 3 dB bandwidth exceeding 50 GHz, low capacitance at 50 femtofarads (fF), and minimal dark current, they are optimized for high-performance applications in longwave fiber-optic communications. The product line offers two distinct flip-chip pad configurations, ensuring they work effortlessly with high-performance TIAs.
Advancements in Data Center Applications
Kou-Wei Wang, Vice President of InP DML & Photodiodes at Coherent, stated, “These photodiodes represent a major advancement in reliability and performance for data center applications. Their high bandwidth and excellent optical characteristics allow our customers to develop high-speed optical transceivers with an additional performance margin.”
Availability of the New Technology
Currently, these high-speed photodiodes are available for sampling, with a full release set for the first quarter of the upcoming year. This availability marks an exciting opportunity for developers to incorporate this advanced technology into their existing systems.
