Abstract

We show how the non-conformal distortions of optical space are connected to the refractive index distributions of isotropic dielectric non-Hermitian media. Using this insight, we design and numerically demonstrate the operation of a broadband unidirectional invisibility cloak. Remarkably, the presence of gain and loss lifts the usual requirement of near zero refractive index values for such cloaks. Our framework provides an unexpected bridge between the fields of transformation optics in isotropic media and non-Hermitian photonics.
