AB - We study the diffraction produced by a slab of purely reflectivePT-symmetric volume Bragg grating that combines modulations ofrefractive index and gain/loss of the same periodicity with a quarter-periodshift between them. Such a complex grating has a directional couplingbetween the different diffraction orders, which allows us to find an analyticsolution for the first three orders of the full Maxwell equations withoutresorting to the paraxial approximation. This is important, because onlywith the full equations can the boundary conditions, allowing for thereflections, be properly implemented. Using our solution we analyzeunidirectional invisibility of such a grating in a wide variety ofconfigurations.
