Abstract

Photonic integrated circuits (PICs) provide potential applications in fields of optical communications and bio-photonic sensors.[1] To prepare PICs with excellent performance, significant progress has been made to develop lead halide perovskite lasers due to their superior fluorescence yields and high absorption coefficient,[2] and their integrations to waveguides have been demonstrated.[3] However, these studies used etching processes for fabrication, which are known to cause defects on the perovskite surfaces. Here, we demonstrated the coupling of on-chip perovskite nanocrystal lasers and the long-range surface plasmon polariton (LRSPP) waveguides by using an etching-free lithographic patterning. This platform can be considered to be a promising tool in optical communications and sensor-related devices.
