In our lab, we use quasiparticles called polaritons to trap infrared light in cavities (size 0.01-1μm) with a size far below the free space wavelength (typically 1-100μm). We couple these polaritons to optical transitions in dimensionally confined quantum mechanical systems, such as quantum wells, wires, and defects. The goal in doing so is to assess whether we can overcome the length scale mismatch between the light and the quantum system, enabling new types of optical components and phenomena.

Work in my group is based around a range of materials, including 2D materials (such as graphene), semiconducting materials (such as gallium arsenide) as well as vibrationally active molecules (including liquids and thin films). The experiments that we use include optical and magnetic measurements, computational techniques, and device fabrication (using cleanroom facilities). I am also committed to building a diverse and inclusive lab, where everyone is welcome and supported by both myself and each other.

The Folland lab is currently recruiting both undergraduate and graduate students for projects. Please contact Prof. Folland if you are interested in getting involved with our work.
