“…Apparently, the non linear behaviour of SOA which is a drawback can be used as a considerate option for an optical gate that is controlled optically. The non linear effects associated with semiconductor optical amplifiers are cross gain modulation, cross phase modulation and four wave mixing [3]. The self phase modulation is one of the nonlinear effect of SOA in which the amplifier output phase is modulated due to the variation of refractive index caused by the change in input signal power.…”

All optical flip flops play an important role in optical networks as well as in the field of optical computing. Optical memories are used for storing decisions in photonic packet routers temporarily. In this paper all optical D-flip flop is designed based on all optical gates. The nonlinear effects such as XGM (Cross Gain Modulation), XPM (Cross Phase Modulation) and FWM (Four Wave Mixing) are used to design all optical gates. We designed the D flip flop based on two logic that are NAND-NAND logic and NAND-NOR logic. The performance of both the designs is analyzed and the functionality of all optical D-flip-flop is verified using the truth table. It is proved that NAND-NAND logic is more effective than NAND-NOR logic.

“…The main nonlinear effects in SOAs, are caused primarily by the change of the carrier density induced by input signals and for-origin carrier dynamics, such as self gain modulation (SGM), self phase modulation (SPM), self induced nonlinear polarization rotation (SPR), cross-gain modulation (XGM), cross-phase modulation (XPM), cross-polarization modulation (XPolM) and four-wave mixing FWM [14].…”

We propose and demonstrate a tunable 50 GHz photonic synthesizer using nonlinearities in a Mach-Zehnder modulator (MZM) in conjunction with the four-wave mixing (FWM) effect in an ultra-long semiconductor optical amplifier (UL-SOA). The operation principle is based on an external modulation scheme using a low phase noise local oscillator (LO) source to multiply the LO frequency in the optical domain. We experimentally demonstrate tunable and low phase noise millimeter-wave (mm-wave) signal generation up to 50 GHz using a low frequency reference LO source. A multiplication of eight-times the LO frequency has been achieved resulting from the nonlinear behavior of the MZM in conjunction with the UL-SOA. Phase noise measurements of the fundamental LO frequency as well as of the generated mm-wave signal with a multiplication factor of N=8 have shown phase noise levels of -96 dBc/Hz and -78 dBc/Hz at 10 kHz offset from the carrier, respectively.

“…This analysis is based on the MNLSE considering the non-linearities in SOA, such as self-phase modulation (SPM), two-photon absorption (TPA), group velocity dispersion (GVD), carrier depletion (CD), carrier heating (CH), spectral-hole burning (SHB), gain spectrum dynamics, and gain saturation in the SOA [5,7]. To solve the MNLSE, the finite-difference beam propagation method (FD-BPM) is used because of its short convergence time and excellent accuracy of the simulated results [8][9][10][11][12][13][14][15][16].…”

a b s t r a c tThis paper presents the pulse propagation and gain saturation characteristics for different input optical pulse shapes with different energy levels in semiconductor optical amplifiers (SOAs). A finite-difference beam propagation method (FD-BPM) is used to solve the modified nonlinear Schrödinger equation (MNLSE) for the simulation of nonlinear optical pulse propagation and gain saturation characteristics in the SOAs. In this MNLSE, the gain spectrum dynamics, gain saturation are taken into account those are depend on the carrier depletion, carrier heating, spectral hole-burning, group velocity dispersion, self-phase modulation and two photon absorption. From this simulation, we obtained the output waveforms and spectra for different input pulse shapes considering different input energy levels. It has shown that the output pulse shape has changed due to the variation of input parameters, such as input pulse shape, input pulse width, and input pulse energy levels. It also shown clearly that the peak position of the output waveforms are shifted toward the leading edge which is due to the gain saturation of the SOA. We also compared the gain saturation characteristics in the SOA for different input pulse shapes.
