| Abstract: | A laser array on the nano‐ and microscale is a key component for integration in photonic devices, but remains a challenge when using semiconductor nanowire lasers. Here we report a low‐threshold lateral‐cavity microlaser, formed between two lateral‐faces of a single‐crystalline organic microbelt (OMB) of 1,4‐dimethoxy‐2,5‐di4′‐(cyano)styryl]benzene (COPV). By cutting a single OMB into six pieces by a top‐down two‐photon processing technique, we successfully fabricated a compact and uniform 1×6 microlaser array along the length direction of the OMB. The microlasers had excellent reproducibility and addressable high precision, thus making them attractive candidates as miniaturized coherent light sources for future nanophotonics. |
