AN INTEGRATED PLANAR OPTICAL DEVICE BASED ON DIGITAL PLANAR HOLOGRAPHY

摘要

An integrated planar optical device having a holographic pattern based on digital planar holography The device consists of a semiconductor substrate that supports a plurality of planar optical elements and a lower cladding layer. The lower cladding layer supports a light-propagating and distributing layer, embedded into which is a plurality of interconnecting pattern elements of a holographic pattern intended for controlling properties and directions of light beams propagating to and from the aforementioned planar optical elements in accordance with the holographic pattern This is achieved by providing specific positions, shapes, and a refractive index of pattern elements that are different from the refractive index of the material of the layer that contains these elements The method of designing and manufacturing the aforementioned pattern is described.
