With the advantage of energy-effectiveness, colloidal self-assembly has been employed to fabricate large-scale photonic crystal. Recently, large scale photonic crystal fabrication research has been done like spin coating method, doctor blade method, spray coating method and roll-to-roll method. They are advantageous to fabricate photonic crystal in large area, however, still, there are problems, such as thickness control and surface defects. Thus, in this paper, a method on applying constant centrifugal force on substrates is proposed to solve the problems. To verify which the method could be a breakthrough, a rotational device applying proposed idea is designed and used in experiments on fabricating photonic crystal. In designing device, to regulate centrifugal force, water is utilized as alleviating the mechanical tolerance. And, in order to transfer the water-induced pressure to the cylinder-substrate, engraved patterns shaped in impeller blade are used in cylinder outer wall. After defining cylinder shape through experiments, it is carried out that fabrication of photonic crystal on substrates of removable cartridges fit into the cylinder coated with PDMS. Under constant rotational speed, photonic crystal is manufactured on substrates, with changing cartridge design, PDMS coating condition, rotational speed and an amount of injected monodispersed colloidal suspension, and eccentricity condition. Through these experiments, fabricated photonic crystals are low defects and have uniform thickness in radial direction, which is on substrates coated with PDMS mixing in 10:1 with 48h solidification, under 2300rpm and 82μL targetting 50μm thickness. Therefore, this new fabrication method has a potential to fix mentioned problems and this device is promising in large-scale fabrication of photonic crystals.
