Abstract: Liquid crystal coupled light modulation includes a light guide to guide light by total internal reflection (TIR), a diffraction grating and a liquid crystal sandwiched between the diffraction grating and the light guide. The liquid crystal has a state with a first refractive index to defeat TIR and another state with a second refractive index to facilitate TIR at a surface of the light guide. The liquid crystal in the first refractive index state is to couple out a portion of the guided light to the diffraction grating and the diffraction grating is to provide diffractive redirection of the coupled portion out of the light modulator.

Abstract: An optical coupling system includes an optical signal source to provide an optical signal from an aperture. The system also includes a substantially planar high-contrast grating (HCG) lens to convert an optical mode of the optical signal to provide a converted optical signal having a mode-isolating intensity profile. The system further includes an optical element to receive the converted optical signal. The optical signal source and the substantially planar HCG lens can be arranged to substantially mitigate coupling of a reflected optical signal associated with the converted optical signal that is reflected from the optical element to the aperture of the optical signal source based on a reflected mode-isolating intensity profile.

Abstract: A light modulator includes a light guide to guide light by total internal reflection, a diffraction grating at a surface of the light guide, and a liquid crystal in contact with the diffraction grating. The liquid crystal has a first state with a first refractive index that substantially matches a refractive index of a material of the diffraction grating to defeat the diffractive coupling. The liquid crystal has a second state with a second refractive index that differs from the first refractive index to facilitate the diffractive coupling.
