Categorical positioning across six photonic-integration axes. POET holds leader status on integration approach (hybrid Si + III-V) and capital efficiency, fast-follower on foundry maturity, limited on customer engagement breadth (NDA-shielded). Direct competitors: Intel SiPh + GF Fotonix at monolithic architecture; Coherent at module-component-layer; HyperLight at TFLN modulator IP layer; LWLG at adjacent EO-polymer material layer.
