Abstract
Computer simulation of characteristics of the liquid crystalline (LC) modulator based on π-cells for 3D applications was performed considering the cohesive energy of LC molecules on orienting surfaces. It is shown that the decrease in the cohesive energy of LC molecules binded to orienting substrates of π-cells, when the spin angle of LC-structure is 0°, leads to significant improvement of their integrated optical characteristics. On the contrary, when the spin angle is 180°, the cohesive energy decrease results in deterioration of their integrated optical characteristics. At the same time, for modulators based on π-cells, both for the LC-structures with the spin angle of 0° and for structures with the spin angle of 180°, the cohesive energy decrease leads to the increase of the total response time of the modulator.
