Zusammenfassung:Polarization rotating (PR) Mach Zehnder Interferometer (MZI) device is proposed based on Si waveguide platform using multimode concept and experimentally demonstrated. Its concept is to use the mode conversion between TE first order and TM fundamental modes. The device is composed of mode converters, multimode directional couplers and PR rib waveguides inserted to the center of each arm waveguide. Fabricated PR MZI device shows good matching in the spectra between TE and TM polarizations in terms of the operation wavelength and the device loss.
