Paper Abstract

We have developed a novel method for simple and quick fabrication of various 2D photonic crystals consisting o polymer rods arranged regularly in air using molds made by laser light. Square- and honeycomb-lattice photonic crystals, in which the radius of a rod, the spacing between nearest-neighbor rods, and the real part of a dielectric constant of the polymer were 22 micrometers , 90-100 micrometers and 3.7, respectively, were created, and far-IR transmission spectra were measured. The experimental and calculated result agreed with each other, indicating that our samples were genuine photonic crystals. In addition to well-known opaque regions in transmission spectra due to photonic band gaps and optical branches of uncoupled mode, we have discovered that the transmission is suppressed drastically at branches with flat dispersion due to the influence of absorption of light.
