Progress in experimental topics included guided wave Optical Bistability, mostly thermal, picosecond switching, studies on quite a number of new materials, optical computing, and pattern recognition using arrays of nonlinear etalons. Theoretical progress ranged from rather practical calculations on device performance, noise effects on switching, and transverse and longitudinal spatial effects to fundamental studies of dynamics, instabilities, and chaos. The Conference also included both theoretical ideas on optical computer architecture and intrinsic OB circuit elements such as as full adder as well as the first demonstration of an intrinsic optical circuit in the form of a cascadable loop with buffered stores. A first demonstration of a simple pattern recognition algorithm using 2 D arrays of spots on a ZnSe interference filter was reported. All-optical signal processing and computing has unique capabilities and much a progress has been made for devices with gain the elusive optical transistor mentioned in the preface of OB2 and cascadable elements implying indefinitely extensible optical restoring logic were reported and provide the first few steps. Attempts to begin to use the massive parallelism and global interconnections look intriguing even with relatively slow devices the alternative approach of serial or even better, parallel picosecond processing is also quite promising.
