Abstract
The helicoidal structures in ferroelectric liquid crystals can be utilized to realize a special phase matching for the second-harmonic generation (SHG) when two counter-propagating fundamental waves are normally incident and the wavelength of the second-harmonic wave is near the selective reflection band edge. In this paper, we report the thickness and polarization dependences of the SHG thus observed. By comparing the experimental results with the theoretical ones developed, good agreement was confirmed.
