A performance study of a logical gate using PPM optical pulse modulation for TDM systems

Nonlinear Binary Codes Derived from Constacyclic Codes

“…The input pulses fundamental solitons with pump power P 0 = 5.18 W which is required for the first order soliton propagation. It is assumed a coupling length L c = 64.30 m and the coupling coefficient is κ = 24.0 km −1 .The critical power calculated is P C = 32.0 W which is above the pump power P 0 [5].…”

Optical cryptography under PPM-PAM modulation based in short optical pulses in an acoustic-optic tunable filter (AOTF)

“…It is possible to have AOTF with 32 channels at 10 Gb/s. It is known that the modulation process could be done in faster velocities like, for instance, 100 Gb/s for the PPM modulation, is reported (Sobrinho et al 2007). …”

“…While emerging asynchronous transfer mode (ATM) switches and Internet Protocol (IP) routers can be used to switch data using the individual channels (typical rates of 2.5 or 10 Gb/s) within a WDM link, this approach requires tens or even hundreds of switch interfaces to terminate a single link with a large number of channels (Vlachos et al 2003). In this way, various optical devices have been studied for the all-optical signal processing, all-optical logical gates, ultrahigh-speed optical telecommunications, alloptical switching, RF photonic signal processing (Vlachos et al 2003;Boscolo et al 2008;Stampoulidis et al 2007;Menezes et al 2007a;Li et al 2008;Menezes et al 2007bMenezes et al , 2009Almeida et al 2007;Sobrinho et al 2008;Zoiros et al 2006;Clavero et al 2004;Fraga et al 2006;Sobrinho et al 2007Sobrinho et al , 2002bSobrinho et al , 2004Onaka et al 2008;Veeriah et al 2007;Sobrinho et al 2006a;Sobrinho et al 2002a;Gao et al 2006;Menezes et al 2006;Ferreira et al 2009), ultrafast metrology, microwave engineering, image processing and optical computing and already several functions can be accomplished within the optical domain, such as optical power division, ultrafast optical switching, optical connections with photonic gateways and all-optical multiplexing (Vlachos et al 2003;Boscolo et al 2008;Stampoulidis et al 2007;Menezes et al 2007a;Li et al 2008;Menezes et al 2007bMenezes et al , 2009Almeida et al 2007;Sobrinho et al 2008;Zoiros et al 2006;Clavero et al 2004;Fraga et al 2006;…”

All-Optical Logic Gates: Designs, Classification, and Comparison

“…Pulses pass through acoustic-optic waveguide that determine the wavelength to be transmitted. The Boolean logic gates are verified by the temporal displacement of the output pulse[24].2.2. All-OpticalGates with SOA.…”
