Advancing Additive Nanomanufacturing of Quantum Optoelectronics

Abstract

The fabrication of quantum optoelectronic devices faces significant challenges due to the limitations of conventional nanomanufacturing techniques, which hinder the precise integration of quantum materials with nanophotonic structures. This dissertation investigates electrohydrodynamic inkjet (EHDIJ) printing as a transformative nanomanufacturing approach that enables additive, high-resolution patterning at the nanoscale. First, EHDIJ printing is used to heterointegrate colloidal emitters onto suspended nanophotonic cavities, enhancing device performance while preserving structural integrity. Next, the technique is refined to achieve deterministic placement of single quantum dots, enabling integration into complex photonic architectures. Finally, EHDIJ printing is applied as a femtoscale reactor for synthesizing single perovskite nanocrystals with spatial and structural precision. These contributions establish EHDIJ printing as a versatile platform that unifies synthesis and integration, offering a scalable path toward sustainable manufacturing of quantum optoelectronic devices. This work opens new possibilities for quantum photonic circuits, on-chip single-photon sources, and hybrid device architectures previously limited by fabrication constraints.
