Error-free all-optical packet switching is demonstrated at 160 Gb/s. The system employs a highly scalable in-band optical labelling, filter-based label extraction, a hybrid-integrated optical flip-flop, and a single SOA-based wavelength converter.

We demonstrate an error-free 160 Gb/s SOA-based optical wavelength converter. This optical wavelength converter can be controlled by a monolithically integrated optical flip-flop memory to switch 80 Gb/s data-packets alloptically. The optical wavelength converter consists of an SOA and an optical filter. Assisting by an optical bandpass filter, an effectively recovery time of 3 ps is achieved i...

An all optical set-reset flip flop is presented that is based on two coupled identical laser diodes. The lasers are coupled so that when one of the lasers lases it quenches lasing in the other laser. The state of the flip flop is determined by which laser is currently lasing. Rate equations are used to model the flip flop and obtain steady state characteristics. The flip flop is experimentally ...

Operation of a novel wavelength selective electro-optic flip-flop is demonstrated. The flip-flop consists of an anti-reflection coated two-section semiconductor laser diode with optical feedback from two fiber Bragg gratings. Electrical set and reset signals cause the lasing output to toggle between two distinct lasing wavelengths with a mode suppression ratio of greater than -35 dBm.

Since there is an increasing demand for fast networks and switches, the electronic data processing imposes a severe bottleneck and all-optical processing techniques will be required in the future. All-optical flip-flops are one of the key components because they can act as temporary memory elements. Several designs have already been demonstrated but they are often relatively slow or complex to ...

Deriving a dynamic model based on the coupled-mode and carrier rate equations, the effects of coupling coefficient and corrugation position on all-optical flip-flops (AOFF) we have analyzed in this paper. Also the self phase modulation (SPM) in the distributed coupling coefficient distributed feedback semiconductor optical amplifier (DCCDFB-SOA) has been implemented. Then the effects of SPM on ...

Abstract Intensity Modulated (IM) optical communication over an LED channel requires the use of a non-negative signal that can also cope with low-pass nature LEDs. For this purpose, dedicated schemes such as Flip-OFDM and Assymetrically Clipped Optical (ACO)-OFDM have been proposed. We derive common mathematical description on which both rely. Exploiting insight, we propose Continuous Phase (CP...
