Paper Abstract

Nonlinear optical properties of chiral liquid crystalline media are in scope of our interest since several years. Our previous observations in the subject were already reported, where the effect of light interaction with chiral nematic structure was examined by reflected-probe-beam technique. The present contribution is a continuation of that work. Now the concept of modulation of light by light is presented as an example of potential application of previously achieved results. This paper just considers the use of reflected- probe-beam arrangement in combination with optical fiber technique for 'in line' controlling of high-intensity light beams. The idea utilizes nonlinear optical effect in combination with selective light reflection in chiral liquid crystals. The preliminary results of experimental examination of the 'all optical modulator' are demonstrated. Also some practical aspects and application problems are defined.
