Abstract Optical trap displays (OTD) are an emerging display technology with the ability to create full-color images in air. Like all volumetric displays, OTDs lack the ability to show virtual images. However, in this paper we show that it is possible to insteadsimulatevirtual images by employing a time-varying perspective projection backdrop. 

Development of a computational technique for the analysis of quasi-normal modes in hybrid-plasmonic resonators is the main goal of this research. Because of the significant computational costs of this analysis, one has to take various symmetries of these resonators into account. In this research, we consider cylindrical symmetry of hybrid-plasmonic ring resonators and implement a body-of-revolution finite-difference time-domain (BOR-FDTD) technique to analyze these resonators. We extend the BOR-FDTD method by proposing two different sets of auxiliary fields to implement multi-term Drude-Lorentz and multi-term Lorentz models in BOR-FDTD. Moreover, we utilize the filter-diagonalization method to accurately compute the complex resonant frequencies of the resonators. This approach improves numerical accuracy and computational time compared to the Fourier transform method used in previous BOR-FDTD methods. Our numerical analysis is verified by a 2D axisymmetric solver in COMSOL Multiphysics. 

This work describes a novel approach to patterning Indium Tin Oxide (ITO) on Polyvinylidene Fluoride (PVDF) using a laser cut Kapton® tape mask for rapid prototyping. Measurements taken before and after experimentation conclude a non-significant change in sheet resistance while using this method to pattern with a p-value of 0.2947 for a two-tailed paired t-test for significance. 

We introduce a solution for enabling vertical parallax in solid-state leaky mode devices by integrating an electro-optic (EO) phased array. We present a simple proof of concept for an acousto-optic (AO)/EO modulator deflecting in two axes and describe how this could be refined and adapted for transparent large-format and near-eye holographic displays. 

In this Note, we describe a test rig for optimizing the trapping parameters of optical trap displays. This rig allows targeted experimentation on software, hardware, and environmental variables. These variables affect the success and robustness of particle trapping. We demonstrate the operation of the rig in a handful of example experiments while achieving an average standard error of less than 1% and an accuracy of over 98% at a reduced size, user overhead, and cost, allowing for rapid development of optical trap display research. 

It will soon be a decade since leaky mode waveguide devices were presented as a solution for holographic video displays. This paper seeks to provide a brief, topical review of advances made during that time. Specifically, we review the new methods and architectures that have been developed over this period. This work draws primarily from papers seeking to present dynamic holographic patterns using mode coupling from indiffused waveguides on lithium niobate. The primary participants during this time period have been groups from the Massachusetts Institute of Technology, Brigham Young University, and Draper. We also describe the challenges that remain. The body of work reviewed speaks to the need for further development, but it also reaffirms that leaky mode waveguides continue to hold a unique place within spatial light modulation for holographic video displays.
