In-plane and Out-of-plane Band-gap Properties of a Two-dimensional Triangular Polymer-based Void Channel Photonic Crystal
Two-dimensional (2D) triangular photonic crystals were fabricated in a solid polymer material by femtosecond laser drilling of void channels. Transverse electric (TE) mode band gaps were found to be wider and located at shorter wavelengths in comparison with transverse magnetic (TM) mode gaps. The polarization- and angle-dependent transmittance spectra provided a way to estimate the void channel cross section and the effective refractive index. The results demonstrate that the two-dimensional...[Show more]
