Abstract
We succeeded in fabrication of two-dimensional photonic lattice structures in a lead-halide perovskite microcavity. Generally it is difficult to uniformly prepare a perovskite film even in a planar form due to its high crystallinity. To overcome this issue, we employed a simple strategy that is a combination of nanoimprint lithography and spin-coating methods. This scheme enables us to fabricate the wide-area two-dimensional photonic lattice in the perovskite active layer that is promising as room-temperature polariton material.
