“…However, a demultiplexer for a real OTDM system needs to be polarization insensitive. Configurations, which enable polarization insensitive FWM are known [46,[54][55][56][57][58], the most practical of which seems to be a polarization diversity scheme with one SOA only, that was demonstrated in a 200 Gbit/s to 6.3 Gbit/s demultiplexing experiment (see section 4.1.4). Up to now, the discussion on FWM was focused on the conventional SOA operation (see section 2.4).…”

“…Four-wave mixing (FWM) in an SOA has widely been used for applications as wavelength converter [54,[96][97][98][99] and in mid-span spectral inversion (MSSI) experiments [55,[100][101][102]. One key advantage of the wavelength converter based on FWM is that several WDM channels can be handled simultaneously [54] and that the data signal can have any modulation format, including phase and frequency modulation.…”

The authors report on all-optical switching devices based on semiconductor optical amplifiers (SOA) in applications for optical time division multiplexing (OTDM) transmission technology. The report includes a discussion on the basic properties of an SOA on the nonlinear processes of cross-phase modulation and four-wave mixing in the SOA used for all-optical switching and on the application of the SOA as demultiplexer add-drop multiplexer clock recovery and wavelength converter. The devices considered here operate at data rates in excess of \Gb80 where electrical signal processing is not available today

“…According to a recent experimental report [2], a transmission of dense wavelength-division multiplexed (DWDM) 22 channels x 21. 4 Gb/s over 10,200 km on the standard single-mode fiber (SSMF) were successfully demonstrated by employing the OPC.…”

“…Most of OPCs convert a signal to its conjugated idler signal through the four-wave mixing (FWM) process in optical fiber (for example, the dispersion-shifted fiber (DSF) [3]), or semiconductor optical amplifier (SOA) [4]. Although the SOA-based OPC, in general, provides better conversion efficiency than the fiber-based OPC owing to its active medium gain, the nonlinear distortion induced by the SOA is quite critical.…”

Optical phase conjugators (OPCs) constructed by dispersion-shifted fiber (DSF), highly nonlinear fiber (HNLF), and new coming bismuth oxide-based nonlinear fiber (Bi-NLF) are evaluated and compared by computer simulation. Under the limitation of commercially available pump power, we show that HNLF-based OPC is preferable for employing in the transmission system owing to its sufficiently high signal quality.

“…The mid-span spectral inversion (MSSI) technique is transparent to both data rate and modulation format and it can compensate both chromatic dispersion and self-phase modulation. Silicon based MSSI is advantageous over previously proposed nonlinear optical media such as periodically poled lithium niobate (PPLN) 13 and semiconductor optical amplifiers (SOA) 14 in terms of cost, reliability, room temperature operation, and integration potential with other silicon based electronics and photonics devices.…”

The strong optical nonlinearity of silicon and tight optical field confinement in silicon waveguides, accompanied by silicon's unique material properties such as high optical damage threshold and thermal conductivity, enable compact nonlinear photonic devices to be fabricated in silicon using cost effective CMOS compatible fabrication technology. By integrating a p-i-n diode into the silicon waveguide, the nonlinear optical loss due to two photon absorption induced free carrier absorption in silicon waveguides can be dramatically reduced, and efficient nonlinear optical devices can be realized on silicon chips for high speed optical communications. In this paper, we report recent development of silicon p-i-n waveguide based nonlinear photonic chips for wavelength conversion and dispersion compensation applications. Wavelength conversion efficiency of -8.5 dB can be achieved in an 8-cm long p-i-n silicon waveguide by four-wave mixing in continuous-wave operation, and chromatic dispersion compensation by mid-span spectral inversion is demonstrated experimentally using silicon spectral inverter at the mid-span of a fiber optical link, achieving transmission of optical data at 40 Gb/s over 320 km of standard fiber with negligible power penalty. The unique advantages of using silicon over previously proposed nonlinear optical media for dispersion compensation are discussed.
