An optical device includes a first substrate and a sub-wavelength form-birefringent metal oxide retarder plate formed on at least a portion of the substrate. A silicon oxide or silicon oxynitride layer contacts at least a surface of the retarder plate, and a second substrate, having at least one micro-electro-mechanical system device, is bonded to the silicon oxide or silicon oxynitride layer via a second silicon oxide or silicon oxynitride layer.
