We demonstrate error-free wavelength conversion at 320 Gb/s by employing a semiconductor optical amplifier that fully recovers in 56 ps. Error-free operation is achieved without using forward error correction technology. We employ optical filtering to select the blue sideband of the spectrum of the probe light, to utilize fast chirp dynamics introduced by the amplifier, and to overcome the slow gain recovery. This leads to an effective recovery ime of less than 1.8 ps for the wavelength converter. The wavelength converter has a simple configuration and is implemented by using fiber-pigtailed components. The concept allows photonic integration.

【期刊论文】Three-State All-Optical Memory Based on Coupled Ring Lasers
刘永, Y. Liu, Student Member, IEEE, M. T. Hill, N. Calabretta, H. deWaardt, G. D. Khoe, Fellow, and H. J. S. Dorren

An all-optical memory with three states is presented. The memory is realized from three coupled ring lasers. The state of the optical memory is determined by the wavelength of the memory's output light. In each state, only one wavelength is dominant. The three-state all-optical memory can be utilized in all-optical packet switches. The concept of the memory is explained and experimental results are presented that demonstrate that a contrast ratio larger than 40 dB between output states of the memory can be obtained.

【期刊论文】All-Optical Buffering Using Laser Neural Networks
刘永, Y. Liu, Student Member, IEEE, M. T. Hill, H. de Waardt, G. D. Khoe, Fellow, and H. J. S. Dorren

We demonstrate an all-optical buffering method that can handle contention of three optical packets.We have employed a laser neural network as an all-optical arbiter that decides whether packet contention takes place. The laser neural network drives a wavelength routing switch that is used to route the data packets into fiber delay lines. Experimental results are presented.

bstract-We discuss an all-optical wavelength converter based on nonlinear polarization rotation in a single semiconductor optical amplifier.We show that inverted and noninverted wavelength conversion can be realized. We also demonstrate this wavelengthconversion concept can operate over a large wavelength range. Experiments show that error-free wavelength conversion can be obtained at a bit rate of 10 Gb/s.

In this letter, we show that optical packets can be routed in an optical fiber by using an optical threshold function that controls a wavelength converter switch. The optical threshold function is made from two coupled lasers. Experimental evidence is given.
