Ridge and buried waveguide structures feature a plurality of trenches disposed proximate the waveguides in order to enhance confinement of an optical signal propagating within the waveguide are described. Additionally, an adiabatic transition region where the distance between trenches and waveguide is featured.

Planar waveguide structure with tightly curved waveguides

A design for a polarization independent ridge waveguide structure is shown. The inventive waveguide structure features discontinuous trenches formed on either side of the waveguide in which the waveguide has a first polarization characteristic absent the trenches and a second polarization characteristic when the trenches are present. The length of the trenches and the distance between the trenches are chosen to provide a desired amount of attenuation to each of the TE and TM modes. Additionally, this method is used to cause a predetermined polarization in order to compensate for the polarization of another optical component.
