A full‐length accumulative photonic crystal fiber (PCF) that is surface‐enhanced Raman scattering (SERS)‐active is achieved by immobilizing Ag nanoparticles inside the air channels of solid‐core and hollow‐core PCFs using a polyelectrolyte‐mediated process. Raman gain in PCFs prevails with coverage density below 0.5 nanoparticle µm −2 . Light attenuation dominates, however, at a higher density. Controlled coverage density and uniformity of nanoparticles is the key to the exploitation of the length benefit of the PCF platform.
