Title (EN) REDUCING ORDERS OF DIFFRACTION PATTERNS
(FR) RÉDUCTION D'ORDRES DE DIAGRAMMES DE DIFFRACTION
Abstract:
(EN) Examples are disclosed relating to reducing orders of diffraction patterns in phase modulating devices. An example phase modulating device includes a phase modulating layer having first and second opposing sides, a common electrode adjacent the first side of the phase modulating layer, a plurality of pixel electrodes adjacent the second side of the phase modulating layer, and blurring material disposed between the phase modulating layer and the pixel electrodes. In the example phase modulating device, the blurring material is configured to smooth phase transitions in the phase modulating layer between localized areas associated with the pixel electrodes, the pixel electrodes have a pixel pitch by which the pixel electrodes are distributed along the phase modulating layer, and the pixel electrodes are separated from one another by an inter-pixel gap (g), where the ratio of the inter-pixel gap to the pixel pitch is between 0.50 and 1.0.
(FR) Selon des modes de réalisation représentatifs, la présente invention concerne la réduction d'ordres de diagrammes de diffraction dans des dispositifs de modulation de phase. Un dispositif de modulation de phase représentatif comporte une couche de modulation de phase comprenant des premier et second côtés opposés, une électrode commune adjacente au premier côté de la couche de modulation de phase, une pluralité d'électrodes de pixel adjacentes au second côté de la couche de modulation de phase, et un matériau à effet de flou disposé entre la couche de modulation de phase et les électrodes de pixel. Dans le dispositif de modulation de phase représentatif, le matériau à effet de flou est configuré pour lisser les transitions de phase dans la couche de modulation de phase entre des zones localisées associées aux électrodes de pixel, les électrodes de pixels présentent un pas de pixel grâce auquel les électrodes de pixel sont réparties le long de la couche de modulation de phase, et les électrodes de pixel sont séparées les unes des autres par un espace inter-pixels (g), le rapport entre l'espace inter-pixels sur le pas de pixel étant compris entre 0,50 et 1,0.
