Supraparticle microlasers fabricated by self-assembly of colloidal nanocrystals have great potential as coherent optical sources for integrated photonics. However, their deterministic placement for integration with other photonic elements remains an unsolved challenge. In this work, we demonstrate the manipulation and printing of individual supraparticle microlasers, laying the foundation for their use in more complex photonic integrated circuits. As proof of concept, a microlaser is printed on the side of a SU-8 waveguide and its modes are successfully coupled to the waveguide.
