Abstract

The chiral smectic SC* phase of ferroelectric liquid crystals (FLC) is a unique nonsolid phase where the lack of inversion center allows electric-dipole three-wavemixing processes.1 The magnitude of the second-order nonlinear susceptibility of the FLC is comparable to that of nonlinear crystals.2 Together with the opportunity to control optical properties by electric field, this makes FLC a prospective harmonic-generating material.
