Abstract

We propose a Mach-Zehnder interferometer (MZI) which consists of a taper, a bending waveguide, and two

symmetrical arms. The structure is realized with organic-inorganic hybrid polymer materials and analyzed by a

commercially available RSoft CAD BeamPROP solver. We set the core width for input and output of the

Mach-Zehnder interferometer at 6 μm for single-mode propagation. This interferometer shows an excess loss

of 0.162 dB and has an efficiency of almost 96.4%. We also investigate the polarization dependency of this

interferometer varying the beam incident angles from 0-30 degrees and this investigation suggests that this

MZI shows polarization dependency when the light incident on the launched side of this MZI at for

transverse electric (TE) and transverse magnetic (TM) modes.
