Abstract

In photonic crystal slabs an in-plane photonic crystal is combined with a slab waveguide. Light is then confined in plane by the photonic crystal and out-of-plane by the slab waveguide. The etched structures will cause light to scatter out of the waveguide plane. We studied the out-of-plane scattering losses of these holes using a 2D approximation of this 3D structure, with etched slots instead of holes. Our simulation techniques included mode expansion with PML. We show that the losses increase with higher index contrast, but that with very high index contrasts light can be coupled into lossless Bloch modes.
