Abstract

Problems of the blue phase for practical use are its narrow temperature range less than few degrees Celsius just below the clearing point and its unhomogeneous platelet texture. Appling a polymer stabilization method, we extended temperature range of the blue phase and realized laser oscillation at room temperature. A polymer-stabilized blue phase (PSBP) sample was prepared by UV light irradiation under temperature control to maintain the blue phase. Resultant temperature range of a blue phase was expanded to over 50K in width including room temperature. The lasing threshold of mono-domain PSBP was found to be approximately half of one-dimensional chiral liquid crystal as well as unpolymerized blue phase.
