Optical amplitude multiplexing through parametric amplification in optical fibers

All-Optical Amplitude Multiplexing Through Fiber Parametric Interaction Between Binary Signals

“…This optical labeling operation is illustrated in Fig. 23 and would be useful when binary data is entering the domain of an optical packet switching network (OPSN) and needs to be converted to an optical packet (Abbade et al, 2006a;Abbade et al, 2010a). Yet another possible application is to use OAM-4F and OAM-4P in several stages in a way that binary signals are successively converted into an analog signal (Abbade et al, 2010a).…”

Yet another possible application is to use OAM-4F and OAM-4P in several stages in a way that binary signals are successively converted into an analog signal (Abbade et al, 2010a). For example, OAM-4F could be used to multiplex two binary signals into a quaternary one, which could be combined to another binary signal into an octary one and so on, until the number of levels is high enough to make the signal resemble an analog one.…”

“…We begin by reviewing the fundamentals of FWM and parametric amplification (PA) in Section 2. Then, in Section 3, we discuss two techniques that use FWM (Abbade et al, 2005;Abbade et al, 2006a;Abbade et al, 2006b) and PA (Abbade et al, 2010a;Abbade et al, 2010b;Marconi et al, 2011) to convert two 2-ASK signals into a quaternary amplitude-shift keying (4-ASK) one; named, respectively, OAM-4F and OAM-4P. In Section 4, utilization of FWM and PA to convert two binary signals into a ternary amplitude-shift keying (3-ASK) is approached.…”

Quaternary amplitude optical packets generated by four-wave mixing: Power level optimization

“…1a illustrates the generation of a QAOP by FWM optical amplitude multiplexing [7][8][9][10][11]. A binary label at an optical frequency fj and a binary payload at f 2 (f j < f 2) are power offset and acquire reciprocal extinction ratios (RER) Sj= PIO/P j1 and S2= P 20 /P 2 I. where Pij stands for the power of bit j (0 or I) at t; (i= I, 2).…”

“…A recently proposed technique [7][8] suggests that fiber four-wave mixing (FWM) may optically multiplex a binary label into a binary payload, generating a quaternary amplitude optical packet (QAOP). One of its advantages is that the payload and label are transmitted simultaneously and over the same bandwidth, which is not the case for the serial and SCM approaches.…”
