Abstract
Lines of identical photonic crystals (PhCs) were obtained by the method of intermittent motion of the meniscus during evaporation of a colloidal solution. Periodically repeating ridges consisting of close-packed SiO2 microspheres were formed parallel to the contact line. The height of the ridges strongly depend on the solution concentration. Local transmission measurements were performed to prove that the ridges formed at high concentrations are high enough to show the properties of PhCs. The period of the structures was about 140-300 μm. Both the period and width of the ridges depend on the solution concentration and the evaporation temperature. The obtained lines of PhCs can probably be used as masks for lithography, diffraction optical elements and microscopic chemical sensors.
