Abstract
The development of the techniques to control the light flux parameters directly by the light itself has permitted us to realize the new class of devices designed for completely optical signal processing. These new devices are both one-channel facilities for fiber links (light- control switches, modulators, and optical transistors) and multichannel ones (spatial-time light modulators -- STLM), which are the basic elements for the systems of optical data processing. All of these devices are based on light-control optical elements, in which one light flux or impulse directly controls parameters of another without doing an intermediate conversion into the electric signal and back again. In order to transfer some data from the control light flux to the fundamental one, a certain optical medium is required where the transmission properties depend on the control light. Scientific work on creation of the optical medium has already been carried out for more than 20 years. By now, sensitive media with specific switching energy of E equals 10-6 + 10-8 J/cm2 and switching rate of (nu) <EQ 102 cycles/s (the structure like MLS-liquid crystal) have been created. The devices for multichannel optical data processing -- that is, STLMs -- are implemented on the base of these sensitive media.
