 Research in the Capasso Group spans the full stack of scientific procedures from pure mathematics to numerical simulations, nanofabrication, and system-level integrated devices. Projects are strongly interdisciplinary and fall loosely into the following broad directions:

- [Metasurfaces and flat optics ](/metasurfaces-and-flat-optics)
- [Frequency combs, quantum cascade lasers, and RF photonics](/frequency-combs-quantum-cascade-lasers-and-rf-photonics)
- [Optical microscopy and optical forces](/optical-microscopy-and-optical-forces)
- [Optics of 2D and van der Waals materials](/optics-2d-and-van-der-waals-materials)
- [Terahertz sources](/terahertz-sources)
