Abstract

The method for batch continuous production of polymerized cholesteric liquid crystal (PCLC) microdisks based on centrifugal microfluidics was proposed. The prototype centrifugal microfluidic chip was fabricated by wet-etching technique with a series of ladder-like concentric ring channels which depths decrease radially. Two types of dye-doped PCLC microdisks with different doping procedures were generated by this method, the tunable lasing properties were characterized and corresponding potential applications in micro-cavity laser and optical barcode were demonstrated. The method is also applicable to a broad range of other polymerizable materials.
