Grazing incidence X-ray waveguides have become a well established platform for X-ray quantum optics. In these systems the waveguide mediated collective coupling of the X-rays plays a significant role. Recently a formalism has been developed to describe the collective nuclear response using the classical electromagnetic Green’s function for the waveguide [1,2]. However, so far these works have considered only translationally symmetric systems, and plane wave driving fields. We show that driving the waveguides at forward incidence instead allows for direct excitation of multiple guided modes, with centimetre scale attenuation lengths. In this regime, micro-patches of embedded Mössbauer nuclei absorb and emit collectively into a super-position of these modes, with the resultant radiation field displaying pronounced interference beats on a micrometre scale. By considering variations in the size and positions of the micro-patches, it is feasible to engineer the resultant inter-nuclear coupling, with potential for applications in quantum simulation and experimental exploration of mesoscopic quantum dynamics.
