Abstract: A high contrast grating optical modulation includes an optical modulator at a front surface of a substrate to modulate received light. The high contrast grating optical modulation further includes a high contrast grating (HCG) lens adjacent to a back surface of the substrate opposite to the front surface to focus incident light onto the optical modulator. The substrate is transparent to operational wavelengths of the focused incident light and the modulated light.

Abstract: A sub-wavelength thin-film metal grating is placed inside a liquid crystal variable optical retarder at a selected distance from a reflective electrode to form a reflective half wave plate, thereby reducing polarization dependence of the optical retardation generated by the variable optical retarder. The approach enables to form within the device the reflective half wave plate that is suitably thin without modifying the reflective electrode of the device.
