  • Publication number: 20220342124
    Abstract: An optic having a refractive-index gradient comprises first and second materials. The first material includes at least one nanoparticle species and has a first volume-fraction profile and a first refractive index n1(?) varying in dependence on wavelength ?. The second material includes at least one polymer species and has a second volume-fraction profile and a second refractive index n2(?) varying in dependence on the wavelength ?. The first and second volume-fraction profiles define the refractive-index gradient of the optic, where, for a longer wavelength ?R and a shorter wavelength ?B: n1(?B)?n2(?B) and n1(?R)?n2(?R) differ by less than a threshold T that limits optical power in the optic.
