The primary techniques for all-optical signal processing such as label swapping and data extraction are successfully demonstrated using VPI simulation tool lntroductlon As the speed of telecommunication systems increases and reaches the limit of electronic devices, the demands for all-optical signal processing techniques such as label or packet switching, decision making, regenerating, and basic or complex computing are rapidly increasing. Current communication systems usually require various ailoptical logic gates such as AND, OR, XOR, NAND, NOR, and XNOR. However, their applications are very limited to small numbers [ l , 21. Also, logic implementation techniques are usually limited to mach-zehnder interferometer and fiber-based devices while our logic gates are mostly based on semiconductor optical amplifiers (SOA?. ) In this paper, the primary techniques of all-optical label swapping and data extraction using semiconductor optical amplifiers are demonstrated at 10 Gbps using VPI simulation tool. Operation principles In this paper, to implement the all-optical label swapping and data extraction among various alloptical signal processing techniques, only one mechanism that is cross-gain modulation (XGM) of SOAs is used. To realize the all-optical label swapping, an all-optical XOR gate using two SOAs is utilized. Operation principle of the XOR gate is shown in Fig. 1 [3].","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.

Various material and structural parameters are used, such as the injection current I, the grating reflectivity R/sub g/, the linewidth enhancement factor /spl alpha/, and a/spl xi//V, where a is the tangential coefficient of the linear gain, /spl xi/ is the field confinement factor and V is the volume of the active region. The simulation is performed based on a new time delay model for SLs, which is applicable under strong OFB. The simulation results show that the lasing operation of SLs under strong OFB is classified into continuous wave (CW), chaos and pulsation depending on the operating conditions. The differences and characteristic features of each lasing operation in the regime of strong OFB are given.","PeriodicalId":206987,"journal":{"name":"IEEE/LEOS 3rd International Conference on Numerical Simulation of Semiconductor Optoelectronic Devices, 2003.
