Abstract

Atomic transitions with orthogonal dipole moments can be made to interfere with each other by the use of an anisotropic environment. Here we describe, provide and apply a computational toolbox capable of algorithmically designing three-dimensional photonic environments that enhance the degree of coherence in atomic $\Lambda$ systems. Example optimisation runs yield approximately double the degree of coherence found using simple planar geometries.
