Multipole method for modeling linear defects in photonic woodpiles

Kan, Dougal J.; Asatryan, Ara A.; Poulton, Christopher G.; Botten, Lindsay C.


We extend the multipole method to allow for rod-type defects in woodpiles composed of infinitely long cylinders. A coupled-resonator optical waveguide and a linear waveguide are considered, where each waveguide is embedded in a woodpile cladding. For both structures, low-loss waveguiding is observed (𝑄≈1×10⁴−3×10⁴). Decreasing the radius of the defect rod shifts the transmission resonances to shorter wavelengths. The reflection and transmission coefficients of the woodpile are derived for the...[Show more]
