Abstract
We study light coupling between two photonic crystal waveguides, one of which supports slow light. We show theoretically that a short photonic crystal waveguide between the two that need to be coupled, can lead to a vanishingly small reflectivity. The design relies on the analogy with a λ/4 anti-reflection layer in thin-film optics. We find that some of the usual relationships between the Fresnel coefficients at an interface no longer hold.
