Abstract

Mode-evolutional multi/demultiplexer for few-mode fibers was demonstrated using stacked polymer waveguides. Owing to the stacked structure, TE00, TE10, and TE01 modes, which correspond to LP01, LPeven11 , and LPodd 11 modes, respectively, were selectively excited by the fabricated multiplexer. The mode excitation ratio was evaluated from the near-field patterns of excited modes using a mode analysis method called the averaged interference component method that we have developed. The evaluated mode excitation ratio was ranging from 6.4 to 9.7 dB for both transverse electric (TE) and transverse magnetic (TM) polarizations of first-order TE modes within the center and long wavelength (CL)-band.
