Chiral liquid crystals, chiral photonic gel, chiral photonic-band structures, soft actuator, wavelength tuning Accordingly, this chiral photonic-band structure, which employs the birefringent soft matter of liquid crystals, can produce well-organized dielectric periodicity at the nanometer scale and provide a high-quality stopband for electromagnetic wave propagation. Moreover, a stable and electrically stretchable broadband wavelength change up to 171 nm of the central photonic-band wavelength change ( I i SB c sb ) was observed in a chiral liquid crystal photonic-band structure for the first time.
