"cheap, chip-scale IR source... quantum mechanics' bound-state in the continuum, leveraging specific wave patterns/ resonances within structured material creating optical chips generating coherent, single-wavelength light sources akin to lasers, heated on hot plate... generating 10 to 12μm mid-IR useful for molecular detection/ analysis... coherent single-wavelength essential, as light sources emitting too many wavelengths complicate signal interpretation... cell phones, microscopy, sensing, wireless communication"
