摘要：

Slow light in liquid crystal media offers the way of implementing interferometric measurements in large area, easily reconfigurable and highly sensitive devices. Here we present two different ways of achieving slow light in liquid crystal media, namely, photoisomerization induced transparency in dye-doped chiral liquid crystals and two-wave mixing optical resonance in pure nematics. The two mechanisms arise from absorption, respectively, refractive index gratings induced in the medium. Doppler shift measurements and adaptive holography are shown as examples of optical sensing applications.
