Digitally Programmable Photochromic Hydrogel Contact Lenses as Light-Adaptive Artificial Irises
Asad Nauman, Tristen Moncada, Guli Gulinihali +3
Excessive exposure to ultraviolet (UV) radiation is associated with a range of ocular pathologies, motivating the development of soft optical devices that can dynamically regulate…
Dispersion Control in Micromechanical Evanescent Optical Modulators
Karl Johnson, John Hong, Tallis Chang +8
Efficient, low-loss, and versatile optical modulators are a critical ingredient for practical integrated photonic systems. Modulators based on micro-electromechanical systems (MEMS…
Scaling Routers with In-Package Optics and High-Bandwidth Memories
Isaac Keslassy, Ilay Yavlovich, Jose Yallouz +3
This paper aims to apply two major scaling transformations from the computing packaging industry to internet routers: the heterogeneous integration of high-bandwidth memories (HBMs…
Panel-Scale Reconfigurable Photonic Interconnects for Scalable AI Computation
Tzu-Chien Hsueh, Bill Lin, Zijun Chen +1
Panel-scale reconfigurable photonic interconnects on a glass substrate up to 500-mm x 500-mm or larger are envisioned by proposing a novel photonic switch fabric that enables all d…
Polarization-Sensitive Diffractive Optics and Metasurfaces: "Past is Prologue"
Noah A. Rubin, Yeshaiahu Fainman
Polarization control and switchability are among the most unique features of "metasurfaces" as compared with diffractive optics technologies of the past. Here, we review how the po…
Interferometric modal splitting enables a broadband, dual-polarization on-chip spectrometer
Karl Johnson, Vladimir Fedorov, Dmitrii Belogolovskii +3
The modal dispersion of waveguides often limits integrated photonic devices to operation with a single polarization state. This presents a challenge for sensing and spectroscopy ap…
