Abstract:

In recent years, atomically thin transition metal dichalcogenides (TMDs) have become one of the most attractive van der Waals materials due to their unique electronic, optical and excitonic properties. The direct band gap and strong excitonic effect make them ideal materials for studying the interaction between light and matter. When coupled with optical microcavities, these materials can form exciton polaritons, which are hybrids of light and matter. Optical microcavities provide a powerful platform for achieving strong coupling between excitons and photons in TMDs, enhancing the interaction between light and matter by confining light to a small volume, thereby achieving stronger coupling and better control of optical properties. Due to advantages such as high quality factor, tunable resonant frequency, and confinement of light to a specific wavelength range, optical microcavities, when coupled with TMD materials, enable the exploration of polaritonic physics and the development of new optoelectronic devices.

This seminar will discuss various optical structures that strongly couple to TMD materials and introduce related device applications and future development directions.
