(a) Schematic showing sample structure and experimental geometry of our highly nonlinear optical polymer 2D PhC slab waveguide. The patterned layer is a square lattice of 360-nm-diameter circular air holes with a lattice constant of 650 nm. (b) Linear fluorescence spectrum for the two-photon absorbing molecule used in the core of the 2D PhC structure. The inset shows transmittance spectrum of the molecule and its molecular structure. (c) SEM image showing cross section of fabricated 2D PhC waveguide.
Incidence-angle dependence of TPEF intensity at 486 nm for the highly nonlinear optical polymer 2D PhC slab waveguide.
Angular dependence of the linear reflectivity of the 2D PhC waveguide at a fixed wavelength of 800 nm along the direction.
Photonic band structure of the highly nonlinear optical polymer PhC slab waveguide with metallic cladding along the line calculated by the 3D FDTD method (open green squares). The experimentally probed positions (closed black circles) of the resonance band modes in the polarized angular-resolved reflectivity are indexed as points and .
