Abstract :
A new nonlinear mechanism, believed to be thermal in origin, has been observed in organic photochromic materials, permitting the observation of bistability under single-wavelength illumination. Externally switched combinatorial logic elements have been fabricated, and a first demonstration has been made cascaded elements in these materials.
