PITTSBURGH, Nov. 18, 2024 (GLOBE NEWSWIRE) — Coherent Corp. (NYSE: COHR), a global leader in high-performance optical networking solutions, has announced the production release of high-speed indium phosphide (InP) photodiodes.

Designed for use in the next generation of 800G and 1.6T transceivers with 200 Gb/s PAM4 optical lanes, and available in both singlet and 1×4 array configurations with integrated lenses, they provide efficient optical coupling and compatibility with all major 4-channel and 8-channel transimpedance amplifiers (TIA).

Featuring a wide optical response from 900 nm to 1650 nm and high responsivity at 1310 nm, these RoHS-compliant devices have a 3 dB bandwidth greater than 50 GHz, a low capacitance of 50 femtofarads (fF), and low dark current. The photodiode arrays are available in two different flip-chip pad configurations for compatibility with high-performance TIAs and are engineered to meet the demanding requirements of longwave fiber-optic communication systems.

“These photodiodes represent a major advancement in reliability and performance for data center applications,” said Kou-Wei Wang, Vice President, InP DML & Photodiodes at Coherent. “Their high bandwidth and excellent optical characteristics allow our customers to develop high-speed optical transceivers with an additional performance margin.”

These high-speed photodiodes are currently available in sample quantities, with general availability planned for Q1 2025.
