چکیده

We demonstrate serial-to-parallel conversion of 40 Gbps optical time division multiplexed (OTDM) signal to 4x10 Gbps wavelength divisionmultiplexed (WDM) individual channels by using Optical Fourier Transformation (OFT) method. OFT is also called time lens technique and it is implemented by the combination of dispersive fiber and phase modulation. In this research, electro-optic phase modulator (EOM) is used as time lens. As our investigations, simulation results and bit error rate (BER) measurements are expressed.

High-speed optical time-division-multiplexed/WDM networks and their network elements based on regenerative all-optical ultrafast wavelength converters

We describe an optical time-division-multiplexed (OTDM)/WDM network architecture that integrates high-speed optical time-division multiplexing at speeds of 40 Gbit/s and higher with lower-bit-rate WDM channels. An ultrafast wavelength converter is used as a regenerative multifunction building block for OTDM multiplexing, WDM-to-OTDM and OTDM-to-WDM transmultiplexing, OTDM/WDM multicasting, OTDM...

Analysis of WDM and OTDM 256-QAM for 1 Tb/s Transmission Link

We provide feasibility study of building a 1 Tb/s (16×4.375 Gbaud) Pol-Mux 256-QAM, 10 km link using WDM and OTDM. WDM meets the SNR requirement, but OTDM does not and has to reduce tributary count. © 2013 Optical Society of America OCIS codes: (060.2330) Fiber optics communications; (060.4080) Modulation; (060.4230) Multiplexing

Broadcast-and-Select Switching System Based on Optical Time-Division Multiplexing (OTDM) Technology∗

This paper presents large capacity switching systems for a local network using the broadcast-and-select (B&S) architecture. The B&S switching system, based on optical time-division multiplexing (OTDM), can provide several hundreds of Gbit/s by using a nonlinear optical switch as the timechannel selector. Moreover, the combination of OTDM and wavelength-division multiplexing (WDM) can realize th...

Asynchronous Digital Optical Regenerator for 4 x 40 Gbit/s WDM to 160 Gbit/s OTDM Conversion.

We propose and numerically analyse an asynchronous digital optical regenerator using a single-EAM loop and a novel neighbor-combine approach. It effectively re-synchronizes input signals with arbitrary phases to the local clock, and regenerates signals with high amplitude fluctuation and polarization mode dispersion. We demonstrate the application of this regenerator for 4x40 Gbit/s WDM to 160 ...

Ultra-high-speed optical serial-to-parallel data conversion by time-domain optical Fourier transformation in a silicon nanowire.

We demonstrate conversion from 64 × 10 Gbit/s optical time-division multiplexed (OTDM) data to dense wavelength division multiplexed (DWDM) data with 25 GHz spacing. The conversion is achieved by time-domain optical Fourier transformation (OFT) based on four-wave mixing (FWM) in a 3.6 mm long silicon nanowire. A total of 40 out of 64 tributaries of a 64 × 10 Gbit/s OTDM-DPSK data signal are sim...
