title: Intrinsic optical transistor action in homeotropically aligned nematic crystal films.
abstract: We report the observation of intrinsic optical transistor action in a homeotropically aligned nematic liquid-crystal film, resulting from the large nonlinearity associated with the optical Freedericksz transition in the nematic sample. No external feedback is employed.
