摘要
The angular dependent reflection of a monodomain blue phase liquid crystal (BPLC) is investigated. Unlike a cholesteric liquid crystal with single twist structure, a monodomain BPLC exhibits several reflection orders from different crystal planes. As incident angle increases, the first order reflection experiences a blue shift while the second order experiences a red shift. We analyze the physical mechanism of the reflection from six (110) crystal planes. Good agreement between calculated and experimental results is obtained. Undoubtedly, this angular dependency would affect the performance of BPLC photonic devices that require an oblique incidence.
