Abstract

To achieve the modification of photonic band structures and realise the dispersion control towards functional photonic devices, composites of photonic crystal templates with high refractive index material are fabricated. A two-step process is used: 3D polymeric woodpile templates are fabricated by direct laser writing method followed by chemical vapour deposition of MoS2. We observed red shifts of partial bandgaps at the near-infrared region when the thickness of deposited MoS2 films increases. A ∼ 10nm red shift of fundamental and high order bandgap is measured after each 1 nm MoS2 thin film deposition and confirmed by simulations and optical measurements using angle-resolved Fourier imaging spectroscopy system.
