Perovskite waveguides with predefined shapes for nonlinear photonics

Nature Materials, Published online: 27 August 2024; doi:10.1038/s41563-024-01994-x

A versatile microfluidic approach is used to fabricate microstructures of arbitrarily predefined shapes from CsPbBr3 monocrystals. The resulting perovskite structures demonstrate waveguiding capabilities and edge lasing from polariton condensates with highly coherent emitted light. This approach is a first step towards perovskite-based nonlinear integrated photonics.Nature Materials, Published online: 27 August 2024; doi:10.1038/s41563-024-01994-xA versatile microfluidic approach is used to fabricate microstructures of arbitrarily predefined shapes from CsPbBr3 monocrystals.
