Fast electro-optic modulations with sub millisecond response times can be achieved in chiral nematic LCs (flexoelectro-optic responses) or blue phase LCs (Kerr-effect type responses). Here, chirality is usually induced in an otherwise non-chiral host LC.
These advanced electro-optical materials have a huge potential to complement and even replace today's LC technologies. Anyway, many challenges still need to be addressed. Therefore, we have developed fitted experimental techniques to investigate their properties quantitatively, so we can go ahead and improve their properties!
One example, where we investigated how added polymer improved the response properties of hyper twisted chiral nematic LCs can be found here:
