Huawei forced into InP ILS optical design by limited access to high-power lasers

bookwormengr · x · 2026-10-19

A technical discussion of Huawei's 3.2T VCSEL NPO (near-package optics) reveals the company cannot source 300mW+ lasers in volume, forcing an ILS (100-150mW integrated light source) design with a redundant backup laser in case the main one fails. The follow-up asks why InP ILS is used when microVCSEL exists, and what the benefit is.
