Diffractive optics have increasingly captured the attention of the scientific community. Classical diffractive optics are 2D diffractive optical elements (DOEs) and computer-generated holograms (CGHs), which modulate optical waves on a solitary transverse plane along the direction of propagation. However, potential capabilities are missed by the inherent two-dimensional nature of these devices. Previous work has demonstrated that extending the modulation from planar (2D) to volumetric (3D) enables new functionalities, such as generating space-variant functions, multiplexing in the spatial or spectral domain, or enhancing information capacity. Unfortunately, despite significant progress fueled by recent interest in metasurface diffraction, 3D diffractive optics still remains relatively unexplored.This thesis presents research on 3D diffractive optics in various aspects. First, to model and design 3D diffractive optics, two different approaches are presented: full-volume approach and stratified-layer approach. For each of them we analyze strengths and weaknesses. Second, to encode and multiplex information, algorithms are developed to iteratively optimize the volumetric structure to modulate light in the spatial, spectral, and frequency domains. Third, to realize the engineered devices, different methods are used including ultrafast laser direct writing, dynamic spatial light modulator (SLM) implementation, and photolithography.Furthermore, I implemented 3D diffractive optics on a 2D SLM for dynamic operation for the first time. I also encoded multiple pages of information in the azimuthal dimension of 3D diffractive optics, showing a new type of multiplexing scheme, named azimuthal multiplexing. I explore active 3D diffractive optics numerically and experimentally, with the system performance investigated in terms of efficiency, scaling, and limits.
