Abstract: Embodiments of the present disclosure describe waveguides having device structures with multiple portions and methods of forming the waveguide having multiportion device structures. The plurality of device structures are formed having two or more portions. The materials of the plurality of portions are chosen such that impedance matching is enabled between the portions to reduce reflection of light from the optical device.

Abstract: Embodiments of the present disclosure generally relate to metasurface devices and methods of forming metasurfaces. The metasurface devices include a plurality of device structures. Each of the device structures are formed from multiple layers, at least one of which is an impedance matching layer. The impedance matching layer may be formed as either an inner impedance matching layer between the substrate and the device layer or as a separate outer impedance matching layer on top of the device layer. The refractive indices of the impedance matching layers are chosen to be between the refractive index of the mediums on either side of the impedance matching layer.

Abstract: Embodiments of the present disclosure waveguides having device structures with a metallized portion and a method of forming the waveguide having device structures with the metallized portion are described herein. The plurality of device structures are formed having a device portion and a metallized portion. The metallized portion is disposed over at least a device portion surface of the device portion such that a plurality of gaps are disposed between the plurality of device structures.
