Abstract: A compact planar channel four-port drop filter is developed

experimentally and theoretically in the three-dimensional woodpile photonic

crystal having a complete band gap. This consists of two waveguides

separated by a defect in a single layer of the photonic crystal. Frequencies

for channel dropping can be tuned throughout the band gap, by changing the

size of the defect. Quality factors of ~1000 were measured. Simulations

demonstrate directional energy transfer between the input and out put

waveguides, through excitation of fields in the defect region. The planar

nature of the filter is much more amenable to fabrication at optical length

wavelengths.
