# Photonic Crystal HeteroWaveguide Layouts¶

This package provides PCells for photonic crystal heterostructure waveguides on a triangular lattice. Heterowaveguides are concatenations of photonic crystal waveguides with slightly different periods. These can be used to form very high-quality resonators.

 W1HeteroCavity Photonic Crystal Waveguide HeteroCavity consisting of a W1 waveguide with adjusted pitch in the cavity. W1HeteroCavity1Mirror this partial component class forms a Cavity with a single mirror. W1HeteroCavityMulti Photonic Crystal W1 Waveguide with multiple HeteroCavities with adjusted pitch in the cavity.
