In this work, the fabrication and working of a novel waveguide optical isolator for silicon photonic platforms,
operating in the transverse electric (TE) mode, have been presented. The waveguide optical isolator
has been realized using the upper cladding layer of a magneto-optical material and its fabrication
has been performed using the direct bonding technology. The magneto-optical effect seen in planar
waveguides and their polarization dependence has been discussed.
