  We report on the mesoscale fabrication and characterization of polymeric
templates for isotropic photonic materials derived from hyper- uniform point
patterns using direct laser writing in a polymer photoresist. We study
experimentally the microscopic structure by electron microscopy and small angle
light scattering. Reducing the refractive index mismatch by liquid infiltration
we find good agreement between the scattering data and numerical calculations
based on a discrete dipole approximation. Our work demonstrates the feasibility
of fabricating such random designer materials on technologically relevant
length scales.
