An optical component is disclosed. The optical component includes a base adjacent to a light transmitting medium. A waveguide is defined in the light transmitting medium. The waveguide has a thickness of greater than 5 mum measured from the base, and has no or very small polarization dependence. In some instances, the waveguide is a member of an array waveguide grating and is sized to have little or no polarization dependence.
