Upconversion nanoparticles have recently received increasing attention due to their outstanding performance in temperature sensing at the nanoscale. Although much effort has been devoted improve thermal sensitivity, there is no efficient way for achieving significant enhancement.

Active manipulation on absorption takes an essential place in nanophotonic light modulators, which always suffer from static tuning ability, limited depth, and insufficient modulating efficiency. In this study, we propose alternative strategy utilizing the symmetry-protected-type bound state continuum (SPBIC) to satisfy a tunable critical-coupling absorber with high mobility. To demonstrate our concept, illustrate ultrathin absorbing system composed of germanium metasurface monolayer...
