Planarized opal-based microphotonic crystal chips...
have been fabricated by directed evaporation-induced self-assembly of microspheres within geometrically defined surface relief patterns. Using this technique it is possible to control the opal crystal shape, size, and orientation, as well as the crystal’s optical properties and functionality. (G. A. Ozin et al., Adv. Funct.
