We present a 1 2 all-optical packet switch. All the processing of the header information is carried out in the optical domain. The optical headers are recognized by employing the two-pulse correlation principle in a semiconductor laser amplifier in loop optical mirror (SLALOM) configuration. The processed header information is stored in an optical flip-flop memory that is based on a symmetric c...

Due to the increasing growth of processing cores in complex computational systems, all the connection converted bottleneck for all systems. With the protection of progressing and constructing complex photonic connection on chip, optical data transmission is the best choice for replacing with electrical interconnection for the reason of gathering connection with a high bandwidth and insertion lo...

-Understanding the spatio-temporal features of the information processing occurring in any complex neural structure requires the monitoring and analysis of the activity in populations of neurons. Electrophysiological and other mapping techniques have provided important insights into the function of neural circuits and neural populations in many systems. However, there remain limitations with th...

All-optical circuits for computing and information processing could overcome the speed limitations intrinsic to electronics. However, in photonics, very few fundamental 'building blocks' equivalent to those used in multi-functional electronic circuits exist. In this study, we report the first all-optical temporal integrator in a monolithic, integrated platform. Our device--a lightwave 'capacito...

We demonstrate a delay line optical recognizer at 2.5 Gbit/s. Recognition is based on a coherent-to-chaotic light conversion followed by a fiber array correlation filter. Experimental evidence shows performance improvement in comparison with a classical scheme as far as phase noise is concerned. An experimental characterization of the recognizer is reported. Methods for improving the recognitio...

This feature issue of Applied Optics: Information Processing contains 19 papers on Optical Computing. Many of these papers are expanded versions of presentations given at the Optical Society of America's Sixth Topical Meeting on Optical Computing held in Salt Lake City, Utah, in March 1995. This introduction provides a brief historical account of the series of optical computing meetings and a b...

Today’s communication WDM or OTDM networks, packetor circuit-switched, are characterized by hybrid architectures. In these architectures, electronic nodes are connected by optical links and switching is usually performed electronically using optoelectronic devices. However, the relatively low transmission bandwidth of the electronics and the associated optoelectronic interfaces, present an obst...
