Optical Correlation Using Four Wave Mixing in a Highly Nonlinear Fibre for Real-Time Serialized Ultrafast Systems

Shalihah F., Mitchell A., Bui L.

International Journal of Electronics and Telecommunications

2013

Vol. 59, No. 3

207-212

A method of all-optical correlation is proposed using the nonlinear phenomena Four Wave Mixing (FWM) of two different signals. The method shows a serial solution where correlation of an ultrafast real-time serialized broadband source is demonstrated using a Highly Non-Linear Fibre (HNLF) with correlation rate reaching 200MHz.

All-optical 4-bit parity checker design

Srivastava V. K., Priye V.

Vol. 41, nr 1

157--164

A new configuration of all-optical 4-bit parity checker is proposed that incorporates six semiconductor optical amplifiers (SOAs). The proposed 4-bit parity generator is numerically simulated by solving nonlinear coupled equations that explain the cross gain modulation (XGM) effect in individual SOAs. The full design is easy to understand. The outputs can be tested at every step with the help of waveforms. This makes easy error analysis of the circuit. The fault detection and correction can be made comfortably. This design proves that when we reach up to chip level design, the economical circuit is integration capable.

All-Optical Techniques Enabling Packet Switching with Label Processing and Label Rewriting

Jung H., Llorente J. H., Tangdiongga E., Koonen T., Dorren H.

Journal of Telecommunications and Information Technology

2009

nr 1

20-28

Scalability of packet switched cross-connects that utilize all-optical signal processing is a crucial issue that eventually determines the future role of photonic signal processing in optical networks. After reviewing several labeling techniques, we discuss label stacking and label swapping techniques and their benefits for scalable optical packet switched nodes. All-optical devices for implementing the packet switch based on the labeling techniques will be described. Finally, we present a 1×4 all-optical packet switch based on label swapping technique that utilizes a scalable and asynchronous label processor and label rewriter. Error-free operation indicates a potential utilization of the swapping technique in a multihop packet-switched network.
