We describe a novel all-optical hybrid mode-division multiplexing (MDM) -optical code division multiplexing (OCDM) architecture for future flexible access network. We successfully demonstrate, for the first time, an asynchronous on-off keying (OOK) modulation, 2 mode x 4 code x 10 Gbps transmission over 2km two mode fiber (TMF), without dispersion compensation at single wavelength, by using 16-chip (200 Gchip/s), 16-phase-shift keyed (PSK) optical codes (OC) generated by a multiport encoder/decoder (E/D) and an optical mode multiplexer/demultiplexer (MMUX/MDeMUX). We also analytically and experimentally evaluate the mode crosstalk tolerance as a function of the LP01 and LP11 modes.
This paper describes summary and recent achievements of Lambda Utility Project, which is one of the major Photonic Network R&D Projects supported by the Ministry of Internal Affairs and Communications (MIC) and National Institute of Information and Communications Technology (NICT) Japan.
We show that, in addition to a stable single soliton,
a dispersion-managed system can also support stable bi-solitons.
The system parameters in which the bi-solitons can exist are also studied. In addition, we propose novel error preventable line-coding
schemes in which binary data are assigned to bi-solitons
and single dispersion-managed solitons. By using the schemes,
impairments arising from intra-channel interactions can be
drastically reduced compared with the conventional scheme for
the same bit rate.
A simple method is developed to analyze the bent waveguide, which is described in the cylindrical coordinate system. By means of this method based on the Galerkin method, the sampling spacing can be chosen arbitrarily and it is possible to treat narrow beams. In addition we introduce the absorber using the graded lossy medium. As this lossy absorber can remove the radiation wave from the bend, so we can use the finite computational window. The lightwave propagating phenomena in the uniformly bent slab waveguide and in the nonlinear slab waveguide are demonstrated
