Abstract :
We propose and experimentally demonstrate a novel compact and integrated terahertz wave waveguide, which consists of silicon photonic crystals with triangular lattice and a line defect waveguide in photonic crystal (PC) slabs. We also directly measured the propagation loss of the line defect waveguides and obtained a value of 0.99dB/mm. The observed waveguiding characteristics agree very well with two-dimensional finite difference time-domain calculations.
