Simultaneous RGB reflections from single-pitched cholesteric liquid crystal films with Fibonaccian defects

We introduce quasi-periodic Fibonaccian phase defects into single-pitched cholesteric liquid crystalline systems. Numerical simulations of reflection spectra from the proposed systems demonstrate simultaneous red, green, and blue reflections or multiple photonic band gaps. Fundamental optical properties are discussed as functions of phase jump (orientational defect angles), unit lengths and the orders of Fibonacci systems. (c) 2007 Optical Society of America.
