“…For instance, optical components characterized by high operation rate can carry out some functions very fast, while the electronic components can realize the complex computations using buffers and memory [46]. In optical networks, the bandwidth mismatch between optical transmission and electronic routers requires a different optical signal processing and the study of the optical packet switching (OPS) [47]. The packet switching is used when it is necessary to select a packet of tens or hundreds of bits from a bit stream [48].…”

Quantum dot-semiconductor optical amplifiers (QD-SOA) attracted strong interest for applications in optical communications and in all-optical signal processing due to their high operation rate, strong nonlinearity, small gain recovery time of about few picoseconds, broadband gain, low injection current and low noise figure (NF). In this chapter, we present the theoretical investigation of the gain recovery time acceleration in DQ SOA; the specific features of the cross gain modulation (XGM) in QD-SOA; the influence of the optical injection on the dynamics of QD-SOA based on the QD in a well (QDWELL) structure. We describe the following applications of QD-SOA: the all-optical ultrawideband (UWB) pulse generation based on the Mach-Zehnder interferometer (MZI) with a QD-SOA; the ultra-fast all-optical signal processor based on QD-SOA-MZI; the ultra-fast all-optical memory based on QD-SOA. The contents of the chapter are mainly based on the original results.

“…Consider the architecture and operation principle of the all-optical packet switch. The scheme of the 1 Â 2 all-optical packet switch is shown in Figure 1 [3,5,7]. The all-optical packet switch consists of three functional blocks: the all-optical header-processing block, the all-optical flipflop memory block, and the WC block [7].…”

“…The all-optical packet switch consists of three functional blocks: the all-optical header-processing block, the all-optical flipflop memory block, and the WC block [7]. All-optical header processing can be realized by using the different methods such as tunable Bragg gratings, FWM in a SOA, terahertz optical asymmetric demultiplexers (TOAD), two-pulse correlation in a semiconductor laser amplifier in a loop optical mirror (SLALOM) [5,7].

All-optical signal processing is characterized by high bit-rate, power efficiency, high bandwidth, and transparency. All-optical logic gates are basic logic units for the alloptical signal processing implementation. Typically, all-optical gates are based on strong optical nonlinearities related in particular to semiconductor optical amplifiers (SOA). We briefly review the state of art in the field of all-optical logic gates and all-optical memory. In the original part, we discuss the ultrafast all-optical memory loop based on the Mach-Zehnder interferometer (MZI) with quantum dot (QD) semiconductor optical amplifier (SOA) in each arm.
