All-optical Mach-Zehnder interferometer wavelength converters and switches with integrated data- and control-signal separation scheme

Mach–Zehnder interferometer-based tree architecture for all-optical logic and arithmetic operations

“…A MZI with two SOAs in two branches (see Fig. 1) can also demultiplex an OTDM signal at high speeds and can be fabricated in the form of an integrated compact chip using the InGaAsP/InP technology [15,24]. The silicaon-silicon technology has also been used to make a compact MZ demultiplexer in a symmetric configuration that was capable of demultiplexing a 168-Gb/s signal [25].…”

Machzehnder Interferometer and it’s Applications

“…Integrated Mach-Zehnder interferometers (MZIs) incorporating semiconductor optical amplifiers SOAs in the interferometer arms have recently been developed as very high-speed all-optical switching devices [23].Various SOA based switching configurations have been demonstrated, such as terahertz optical asymmetric demultiplexers (TOADs) [24],ultrafast nonlinear interferometers(UNIs) [25] and Mach Zehnder Interferometers [26][27][28], out of which MZI switches are most efficient. An MZI with two SOAs in two branches(see Fig.8) can also demultiplex an OTDM signal at high speeds and can be fabricated in the form of an integrated compact chip using InGaAsP/InP technology [26,31].MZI switches have demonstrated single-channel OTDMs at up to 168Gb/s and might even be used for higher data rates [29][30]. MZI-SOA switch is utilized for designing a tree-net architecture in all-optical domain, which is successfully exploited for all-optical logic and arithmetic operations (halfadder, half-subtractor, full-adder, full-subtractor, data comparator) [23] …”

Analysis of Leakage Losses in One-Dimensional Photonic Crystal Coupled Resonator Optical Waveguide Using 3-D Finite Element Method

“…Especially, optical delay lines have emerged as key components for future optical networks and information processing systems. There is a wide range of applications of optical delay lines, such as optical buffers [5], optical regenerators [6], wavelength converters [7], and optical delay-line filters [8]. CROWs are attractive for these applications because of their specific small group velocity and zero group velocity dispersion (GVD) at the transmission miniband [9]- [19].…”
