All-optical packet-drop demonstration using 100-Gb/s words by integrating fiber-based components

All-Optical Header Processing using Direct Modulation of a Fabry-Perot Laser Diode for All-Optical Packet Switching

“…Recently, a number of AOPS schemes have been proposed. In the schemes, the headers of the packets are extracted optically [2]- [4] and processed in the optical domain [2]- [3] or in the electrical domain [4]. The nonlinear optical loop mirror has been an efficient method for implementing AOPS [2]- [3].…”

Performance analysis of the all‐optical XOR gate using SOA‐MZI with a differential modulation scheme

“…The all-optical XOR gates may be classified into two types, depending on the methodology used to achieve the nonlinear operation of the logic devices: (i) fiber nonlinearity-based logic gates [2] and (ii) semiconductor optical amplifier (SOA)-based logic gates [3][4][5][6][7][8][9]. Logic gates using the integrated SOA-based Mach-Zehnder interferometer (SOA-MZI) [8,9] are attractive due to their simple structure, stable and efficient operation, cascading capability, and easy implementation as compared with fiber-based logic gates.…”

“…Recently, the advent of micro-electro-mechanical system (MEMS) technology has made it possible to realize various integrated micro-scale passives [1,2]. Even though many striplines have relatively simple structures and are easy to fabricate, most of them may not be appropriate for use in current wireless communication schemes where most carrier frequencies are below the 10-GHz range, such as Bluetooth or wireless LAN, because the guided wavelength at those frequency ranges is too long to achieve compact-size realization.…”

30 Gb/s all-optical clock recovery circuit

“…N the recent past, there has been an intense effort in the demonstration and deployment of very high capacity WDM/TDM network transmission systems and ultrahigh-speed all-optical digital logic circuits [1], [2]. In order to ensure data synchronization in these applications, it is of crucial importance to be able to generate a high quality local clock in the presence of jittered signal.…”
