“…Furthermore, it is important to note that the parameter space affecting eye quality is large with many adjustable parameters. More extensive measurements and possibly the development of more systematic exploration of experimental parameters could yield improved eye quality [31]. Captured bit sequences for data input (A), wavelength converted data input (B), as well as for the AND result, are shown in Fig.…”

We demonstrate logic functionalities in a high-speed all-optical logic circuit based on differential Mach-Zehnder interferometers with semiconductor optical amplifiers as the nonlinear optical elements. The circuit, implemented by hybrid integration of the semiconductor optical amplifiers on a planar lightwave circuit platform fabricated in silica glass, can be flexibly configured to realize a variety of Boolean logic gates. We present both simulations and experimental demonstrations of cascaded all-optical operations for 80-Gb/s on-off keyed data.

“…The control signal had at least one order of magnitude higher than the signal to be switched, and provided in the best scenarios extinction ratios (ERs) of up to 30 dB [5]. Another option was to use SOAs with interferometers [6][7][8], which implied incorporating two or more SOAs. The switching operation was then achieved by the influence of a strong control signal introduced into one arm of the interferometer configuration causing depletion of carriers in the SOA, resulting in gain saturation and modification of the refractive index.…”

We experimentally demonstrate, for the first time, an all-optical switch in a phase-sensitive fiber optic parametric amplifier operated in saturation. We study the effect of phase variation of the signal and idler waves on the pump power depletion. By changing the phase of a 0.9 mW signal/idler pair wave by π/2 rad, a pump power extinction ratio of 30.4 dB is achieved. Static and dynamic characterizations are also performed and time domain results presented.

“…SOAs require high biasing current and are expensive [15]. To overcome the higher cost and high driving current requirements, optical units such as gates and switches have been proposed using commercially available multi-mode Fabry-Pérot laser diodes (MMFP-LD) [16][17][18] and especially designed single mode Fabry-Pérot laser diodes [19][20][21]. But all these techniques require input control signal to be high for the entire period of data to be blocked at the output ports.…”

We propose and demonstrate a novel scheme for short pulse controlled all-optical switch using external cavity based single mode Fabry- Pérot laser diode (SMFP-LD). The proposed scheme consists of control unit and switching unit as two essential blocks. The basic principle of the proposed scheme is the optical bistability property of SMFP-LD for the control unit and the suppression of the dominant beam of SMFP-LD with injection locking for the switching unit. We also present the analysis of hysteresis width and rising/falling time with change in wavelength detuning which helps to find the optimum wavelength detuning value and power of light beams at different stages of the proposed scheme that gives wide input dynamic power range, high ON/OFF contrast ratio, and low rising/falling time. Input data of 10 Gb/s Non Return to Zero (NRZ) signal is switched at output ports depending upon the control signal generated by the control unit, which comprises of optical SR latch. Output waveforms, clear eye diagrams with extinction ratio of about 11 dB, rising/falling time of about 30 ps and 40 ps, and bit error rate (BER) are measured to validate proposed scheme. No noise floor is observed at output ports up to BER of 10-(12) and the maximum power penalty recorded is about 1.7 dB at a BER of 10-(9) which shows good performance of the proposed short pulse controlled optical switch using SMFP-LDs.
