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.

“…To distinguish these channels from one another and send them to their appropriate users, a proper photonic device is required at the user end of the network. Mach-Zehnder interferometers (MZI) [5,6], multimode interference (MMI) couplers [7][8][9], Y-branch devices [10,11], ring resonators [12][13][14][15], and other solutions can all be used to create optical demultiplexers based on different optical platforms, which are a crucial components of communication networks [16][17][18][19]. Moreover, small size and low crosstalk demultiplexer devices may have advantages in quantum information processing and quantum communication [20][21][22].…”

Herein, a numerical analysis of a 1 × 2 demultiplexer based on a silica-titania integrated photonics platform is conducted via the finite element method. The structure is composed of two coupled racetrack microrings (RTMRs) and a subwavelength grating (SWG) structure for the demultiplexing of 1310 nm and 1550 nm telecommunication wavelengths. The material platform selected for this design is highly attractive due to its refined optical, physical, and chemical properties. Moreover, silica-titania sol-gel thin-films can be deposited on glass substrates with the dip-coating method. The proposed device has a small footprint of 84 × 125 μm2 and offers crosstalk as low as ~−6.6 dB and ~−9.04 dB for 1550 nm and 1310 nm, respectively. We are convinced that this study promotes the use of the silica-titania platform for the development of low-cost on-chip optical communication devices for signal multiplexing and demultiplexing.

Multidimensional multiplexing technologies have been proven to be a promising scheme to meet the demands of high‐capacity optical interconnects and optical processing networks. However, challenges remain to realize multidimensional hybrid multiplexing data transmission and signal processing between few‐mode fiber transmission links and on‐chip optical processing networks, since the optical coupling between fiber and chip is almost exclusively in the single‐mode regime. Here, a multidimensional fiber‐to‐chip optical processing system is proposed and demonstrated for hybrid wavelength‐, mode‐, and polarization‐division multiplexing signals, where multidimensional coupling between few‐mode fiber transmission link and on‐chip multi‐mode processing network is realized by using a 3D photonic integrated (de)multiplexers on a glass chip as well as 2D photonic integrated (de)multiplexers on a silicon chip, and the on‐chip multidimensional optical processing network composed by parallel cascaded micro‐ring resonator array performs a function of reconfigurable optical add/drop multiplexer. By operating wavelength‐division multiplexing in conjunction with mode‐division multiplexing and polarization‐division multiplexing, the communication bandwidth of fiber‐to‐chip optical processing systems can be further scaled.
