Abstract
We present TE transmission measurements of photonic crystal waveguides with high hole radius to period
ratio r/Λ=0.388. This geometry introduces a unique low loss transmission band in addition to the traditional
PhC guiding band and very sharp transmission edges for devices with a length of 50 μm or longer. Finite
difference time domain and plane wave expansion simulations confirm the results and show that the
sharpness of the cutoffs can be explained by the spectral shape of the guiding mode in the band diagram.
