212Gbps high-power EML for 800G artificial intelligence optical transmissions
Main Article Content
Abstract
Abstract
We present a high-power, high-speed 212Gbps four-level Pulse Amplitude Modulation (PAM4) Electro-absorption Modulated Laser (EML) designed for 800G LR4 optical transmission and Artificial Intelligence (AI) applications. The Lan wavelength division multiplexing (LWDM) EML channels, operating at wavelengths of 1295.56 nm, 1300.05 nm, 1304.58 nm, and 1309.14 nm in 800G LR4 optical transceivers, exhibit clear eye openings even after 10km of transmission. Our 212Gbps PAM4 LWDM EMLs demonstrate high bandwidth, high extinction ratio, high power, and high energy efficiency, making them suitable for 10km transmission and environmentally friendly connectivity.
