Supersymmetric photonics: From mode converters to a new class of transformation optics

We provide a brief introduction to supersymmetric photonics and present our newest theoretical findings and experimental results on SUSY mode conversion and the scattering dynamics of light propagating in optical SUSY partner structures. Finally, we show how these notions can be harnessed in a SUSY-inspired extension of transformation optics, enabling the substitution of high-refractive-index arrangements with low-contrast equivalent structures that exhibit identical reflection and transmission properties.
