Abstract

In this paper, a hybrid mode and polarization division (MDM-PDM) (de)multiplexer based on a buried strip waveguide, operating at 1550 nm, is proposed on the silicon-on-insulator platform. The proposed device can (de)multiplex three quasi-transverse electric and two quasi-transverse magnetic modes of a multimode waveguide concurrently. The multiplexing and demultiplexing operations are achieved by coupling the multimode waveguide modes with the fundamental modes of the single-mode waveguides. The couplings between the modes are realized by employing grating structures in between the multimode and single-mode waveguides. A 2.5D finite-difference time-domain simulation technique is used to examine the performance of the device. An insertion loss of $ \gt\!\; - {0.76}\;{\rm dB}$, return loss of $ \lt\!\; - {11.23}\;{\rm dB}$, and crosstalk of $ \lt\!\; - {12.42}\;{\rm dB}$ are obtained for the proposed hybrid MDM-PDM (de)multiplexer. Moreover, the fabrication tolerance of the proposed device structure is studied by keeping the center-to-center distance between the waveguides constant and by varying the waveguide width.
