Sivers / SIVEF: A Laser-Source Bottleneck Candidate in AI Photonics

Sivers Semiconductors is easy to label as AI photonics, CPO, 1.6T, SATCOM, or defense. The cleaner first-principles view is narrower: it is not a GPU vendor, switch ASIC vendor, full optical-module vendor, or hyperscaler network architect. It combines two enabling component layers: high-power DFB/CW laser arrays in Photonics and mmWave RFIC/beamforming technology in Wireless.

POET / MXL / HIMX: three layers of AI interconnect optionality

POET, MXL and HIMX can all be mapped to AI interconnect, optics, CPO or edge AI, but the first-principles layers are different. POET is a manufacturing-platform option: can Optical Interposer / EOI move optical-engine production closer to wafer-scale integration? MXL is the signal-chain layer: optical modules and AI data-center links need PAM4 DSPs, TIAs and retimers. HIMX is a display and ultra-low-power sensing company with AR, WiseEye and CPO optionality through FOCI.
