Low-Power Optical Reorientation in Dyed Nematics

Research output: Contribution to journalArticlepeer-review

Abstract / Description of output

The optical reorientation process in nematic guest-host mixtures is investigated. It is found that for certain dyes the optical Freedericksz threshold is two orders of magnitude lower as in the pure host. The observations can be interpreted in terms of an enhanced optical torque which increases with the dye concentration.
