All-optical tunable on-chip plasmon-induced transparency is realized in integrated plasmonic circuits based on two surface-plasmon-polaritons absorption induced polymerization of SU-8 photoresist. Owing to the enhanced interaction between surface plasmon polaritons and SU-8 guaranteed by the slow light effect around the transparency window and the strong light confinement effect of the plasmonic nanocavity modes, a continuous shift range of 24nm in the central wavelength of the transparency window was obtained. The threshold power of the two surface-plasmon-polaritons absorption induced polymerization of SU-8 was as low as 100 mu W, which is three orders of magnitude less than previous reports.
