Abstract

Composite materials having colloidal photonic crystals patterned in substrates for use in different technologies including lab-on-chip and photonic chip technologies. The colloidal crystals are patterned either on or within surface relief patterns in the substrates of the composite materials and each colloidal crystal exhibits Bragg diffraction.
