Research Experience

2020 – Present
Graduate Research Assistant — Safavi-Naeini Group, Stanford University
  • Co-first authored a low-power integrated optical amplifier achieving >17 dB gain at <200 mW — an order-of-magnitude improvement over prior integrated OPAs (Nature, 2026).
  • Demonstrated an on-chip squeezed-light source with full quantum-state tomography on thin-film lithium niobate (Science Advances, 2024).
  • Achieved record-efficiency second-harmonic generation of blue light (456 nm), ~33,000%/W·cm² (Optics Letters, 2022).
  • Contributed to the first integrated frequency-modulated OPO (Nature, 2024) and an integrated quantum optical phase sensor (Nature Communications, 2023).
  • Built the optical setup and PCB for in-situ backpropagation in photonic neural networks (Science, 2023).
2018 – 2019
Undergraduate Research Assistant — Integrated Nanophotonics Lab, KAIST (Advisor: Kyoungsik Yu)
  • Designed programmable photonic integrated circuits using cascaded optical resonators for multi-wavelength unitary transformations (Optics Express, 2021).
