Abstract
An organic optical logic device comprising, as a nonlinear optical medium, a crystal of organic molecules which are excited to a state of electronic excitation with an oscillator strength of at least 1.0 by visible or near-infrared radiation within a region of wavelengths of 0.4 to 1.3 .mu.m operates at room temperature with a low energy at great speed when the electronic excitation of the crystal generates excitons or exciton polaritons having a resonance wavelength of .lambda..sub.0 and the organic optical logic device is operated with a driving light having a wavelength of .lambda..sub.o -50 nm to .lambda..sub.o +50 nm.
