Abstract
Transition metal dichalcogenide(TMD) monolayers and their heterostructures host promising nanoscale light emitters such as single defects and intra/interlayer-excitons. By resonantly coupling these emitters to optical nanocavities, various light-matter interaction phenomena including Purcell enhancement and strong coupling emerge. However, achieving exact matching between cavity and excitonic resonances is difficult mainly because of the inability to precisely control the resonant wavelength of fabricated optical structures. In this work, we demonstrate the use of a cryogenic strain cell to continuously and reversibly tune the optical resonance of GaP nanobeam cavities over a large range. We discuss the merits and challenges of this tuning technique and report our progress in using it to study cavity coupled phenomenon of emitters in monolayer TMD.
