Outline of Research at the Start	Our project proposes a nanophotonic laser design for 2D and QD materials, utilizing a low-dimensional material-coupled metasurface for bound states in the continuum (BIC) to achieve an ultra-high Q factor and significantly reduced radiation loss. This design incorporates high-quality, low-defect, wafer-scale low-dimensional materials that eliminate the need for transfer.
