A Review of Polarization Dependence Applications for Asymmetric Waveguides Vertical Couplers in Compound Semiconductor Indium Phosphide

Chee-Wei Lee

This paper reviews and presents a coherent approach to the design of compact vertical coupler (VC) in InP-based compound semiconductor with variable polarization dependence.  ...  We further demonstrate the single-mesa VC, which simplifies the fabrication process and potentially could improve the process yield, and its integration with a multimode interferometer (MMI).  ...  The deviation of dimension is probably not critical for the MMI, as MMI is a robust device and allows larger fabrication tolerances. However, for the vertical coupler, this is not the case.  ...
