Currently I am reading one research paper regarding silicon based two and four mode division multiplexing for optical data transmission in 2 micrometer waveband. While reading I stuck at one point. How parallel direction coupling of modes working in waveguides? and how modes have their phase matched?
Dr Hina ---please take a look at the following useful links:

We report contra-directional coupler type polarization rotation Bragg gratings using silicon waveguides. Waveguides incorporating a Bragg grating for polarization rotation and having different widths are placed near to each other. A single grating can separate the backward diffraction light. The structure is optimized considering the field strength ratio between waveguides. A distinct polarization rotation wavelength peak is obtained by 3D-FDTD simulation.
