摘要： A photonic processing module (100) comprises a high index-contrast waveguide device comprising a substrate (102), a first layer (104) disposed on the substrate having a first refractive index, and a relatively thin second layer (106) disposed on the first layer. The second layer has a second refractive index providing a high index-contrast with the first layer, and the device includes at least one thin-ridge waveguide element (108) formed in the second layer which supports a guided mode in a longitudinal direction. An optical input port (110) is configured to direct an input beam into a slab mode of the second layer, the beam being directed to propagate at a predetermined angle θ to the longitudinal direction of the thin-ridge waveguide element. The angle θ is associated with a resonant coupling between the slab mode of the second layer and the guided mode of the thin-ridge waveguide element. An output beam is thus generated when the input beam includes one or more optical components corresponding with the resonant coupling. An optical output port (112) is configured to receive the output beam.

摘要： The present disclosure relates to a light guide plate, a backlighting module and a liquid crystal display device. The light guide plate comprises a light guide plate body and an optical waveguide layer located within the light guide plate body. According to technical solutions of the present disclosure, the optical waveguide layer can modulate stray light in the light guide plate into collimated light, such that the collimated light is emitted out from a light exit side of the light guide plate. As compared with an existing approach, with the light guide plate of the present disclosure, a loss of incident light of the light guide plate is reduced, an optical efficiency of the backlighting module is improved, and thereby a display quality of the display device is promoted.

摘要： A color changing or beam steering photonic device, which combines a high contrast metastructure (HCM) having a plurality of high index grating structures, into a low index membrane. In response to physical (or electrical) deformation of the membrane the low index gaps between adjacent grating bars changes which results in changing reflectance and transmission angles for steering a single wavelength of light and for causing a color change in said photonic device when subject to multiple light wavelengths. Deformation can result from direct physical stimulus, conversion from electrical or thermal to physical, and so forth. Refractive index change can also be initiated by carrier injection through electrodes. The apparatus is exemplified for use in color displays, beam steering, labeling micro entities, mechanical deformation sensing, camouflage, anti-counterfeiting, and other fields.
