The research presented in this dissertation focuses on improvements made to lithium niobate leaky-mode modulators for both holographic video and optogenetic applications. The specific improvements found herein are: (1) characterization of leaky-mode modulators to decrease driver bandwidth to match that of commodity graphics processing units, (2) the implementation of surface relief gratings as input couplers to replace rutile prism coupling, (3) the addition of backside surface relief gratings to create an orthogonal output face for the leaky-mode modulator, and (4) the creation of superimposed surface relief gratings in lithium niobate to enable multiple wavelength coupling at a single input angle. These advancements for leaky-mode modulators open avenues in display technologies and optogenetics. As a display technology, the leaky-mode modulator can not only be used more effectively in holographic monitors, but can stand alone as a transparent near-eye display. In regards to optogenetics, these technologies allow for the creation of a highly advanced light delivery method, with multiple illumination angles through non-mechanical steering, a large output area to probe size ratio, and support for simultaneous multiple wavelength output in both common and disparate locations.
