Juanjuan Ren

Juanjuan Ren is a Postdoctoral Researcher in the Department of Physics, Engineering Physics & Astronomy at Queen's University, affiliated with the School of Arts & Science. Her research focuses on nanophotonics, particularly exploring plasmonic systems, quantum emitter interactions, and cavity quantum electrodynamics (QED). She is supervised by Prof. S. Hughes and contributes to cutting-edge studies in chiral photonics, resonator physics, and quantum light-matter interfaces.

Her work addresses topics such as quasinormal mode theory, Purcell factor optimization, and nonlinear optical phenomena in nanoscale systems. Recent studies involve designing novel photonic devices for single-photon sources and squeezed light generation, leveraging dispersive materials and exceptional-point-based systems to control photon behavior. Publications emphasize theoretical frameworks for loss-gain resonators, plasmon linewidth narrowing, and quantum state modulation in coupled systems.

Ren's research bridges quantum optics and nanotechnology, with applications in quantum sensing, optoelectronics, and quantum information processing. She collaborates on topics like evanescent field modulation, photon-exciton coupling enhancement, and topological effects in nanophotonic structures. Despite her postdoctoral role, her work demonstrates significant contributions to advancing fundamental and applied photonics research.
