A quasi-bound state in the continuum (quasi-BIC), which maintains a high Q-factor and localization of the electromagnetic field, is implemented in a dielectric metasurface. A liquid crystal (LC) layer covering the metasurface breaks the mirror symmetry and introduces chirality, leading to a chiral quasi-bound state in the continuum (chiral-BIC). Using the controllability of the LC, a change in circular dichroism (CD) through heating is demonstrated. Additionally, doping the LC with dye molecules enables a low-threshold laser that emits elliptically polarized, temperature-tunable radiation. © 2026 Wiley-VCH GmbH.
