To achieve the modification of photonic band structures
and realize
the dispersion control toward 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 a direct laser writing method followed
by chemical vapor deposition of MoS2. We observed red-shifts
of partial bandgaps at the near-infrared region when the thickness
of deposited MoS2films increases. A ∼10 nm red-shift
of fundamental and high-order bandgap is measured after each 1 nm
MoS2thin film deposition and confirmed by simulations
and optical measurements using an angle-resolved Fourier imaging spectroscopy
system.
