The over-arching mission of the Armani research lab is to develop advanced materials and integrated optical devices that can be used in portable disease diagnostics and telecommunications.

  • Fall 2019 Group Photo

  • A new route to enhance microcavity-based Raman lasing is demonstrated by leveraging a single monolayer of oriented molecules. Work published in: X. Shen*, H. Choi*, et al,  Nature Photonics, (2019). Link:

  • A new method for synthesizing core-shell nanoparticles comprised of gold cores and ZnO shells doped with a range of heavy metals is developed. Work published in: R. Zeto, et al, Journal of Materials Research, (2019). link: DOI: 10.1557/jmr.2019.352

  • Using a silicon oxynitride optical microcavity, an environmentally stable optical frequency comb was demonstrated. Published in D. Chen et al, Applied Physics Letters, 115 (5), 1105 (2019). Link:


  • Cavity enhanced Kerr-frequency comb span is improved by leveraging increased Raman efficiency by adding a Zr dopant. Published in H. Choi et al, Optics Letters 43 (12), (2018). Link:


    A lightweight portable diagnostic for malaria is demonstrated by combining a magnetic collection system with self-referencing spectroscopy. Work published in: S. E McBirney et al, ACS Sensors, (2018). link:


  • Combining small organic molecules with optical cavities, the threshold for optical parametric generation is significantly reduced. Published in X. Shen et al, Science Advances, 4 (1) eaao4507 (2108). Link:

Our research efforts include a wide range of topics including materials synthesis, integrated optics and instrumentation development, and characterization of tissue and disease diagnostics. We also perform a significant amount of computational work to support our experimental efforts. Given the diversity of measurements, we perform experiments on the main campus and at the medical school.

To enable this research breadth, our group members include researchers with diverse academic and research backgrounds, and we have numerous ongoing collaborations, both at USC and at other institutions around the world. The lab also supports a large number of undergraduate researchers as well as high school researchers. We are also very active in a wide range of STEM outreach activities. Financial support comes from several different government agencies and companies as well as philanthropic contributions.

The lab is primarily located in the Viterbi School of Engineering, and it is affiliated (through courtesy appointments in different depts and institutes) with the Dornsife College and the Keck Medical School. The research facilities are located in the newly constructed Michelson Center for Convergent Biosciences.
