“…So all-optical switching functions using Fabry-Perot laser diode (FP-LD) has the new dimension towards the simple and cost effective solution. Various proposed technologies of all optical switches using FP-LD till date are with only one output port whether the data output is present or absent [3]- [5]. In this research, all-optical 1Х2 switching operations are demonstrated.…”

In this paper, an all-optical 1×2 switch is demonstrated based on gain modulation of injection locked Fabry-Perot laser diode (FP-LD). The control circuit generates set and reset states, which are used to perform 1×2 switch function. The switch output state is maintained once it starts to operate, whether the control signal is present or absent. In the experiment, with extinction ratio of 13.2 dB the switch output eye diagram is recorded.

“…A number of optical packet switching has been investigated [1][2][3][4][5][6][7][8]. Utilizing all-optical signal processing to realize optical packet switching is promising [2][3][4][5][6][7], because packet switching could be carried out entirely in the optical domain. This means that the bottleneck of optical-to-electrical-to-optical conversion can be eliminated.…”

We present some progress in the field of optical signal processing that could be utilized in all-optical packet switching. We demonstrate error-free 160 Gb/s optical wavelength conversion employing a single semiconductor optical amplifier. The gain recovery time of the semiconductor optical amplifier is greater than 90 ps. Assisted by an optical bandpass filter, an effective recovery time of 3 ps is achieved in the wavelength converter, which ensures 160 Gb/s operation. This optical wavelength converter can be controlled by a monolithically integrated optical flip-flop memory to route 80 Gb/s data-packets all-optically. The routing is realized without electronic control. The integrated optical flip-flop is based on two-coupled lasers, exhibits single-mode operation, has 35 dB contrast ratio between the states and switches state in about 2 ns. We demonstrate that the integrated flip-flop is able to control the optical wavelength converter up to 160 Gb/s. The system is capable of routing 80 Gb/s data packets with duration of 35 ns, separated by 15 ns of guard time.

All-optical packet switching and label buffering have been demonstrated using multimode interference bistable laser diode optical flip-flops and all-optical Mach-Zehnder interferometer switches. The optical flip-flop buffered the injected optical label for the one packet duration and drove the all-optical switch through cross-phase modulation to switch the optical packet. Error-free operation for output 10-Gb/s optical packets from the switch was obtained with negligible power penalty. The presented packet switching has potential of ultrafast switching and transparency of data rate and format, and will be useful in the future optical packet switching networks.
